4. WHAT CAN ANTENNA GENIUStm DO?
Antenna Geniustm 8x2 v2 Plus is a matrix antenna switch which can route eight antennas to two
radios using a variety of control methods. Software and hardware interlocks - double protection
- prevent the same antenna from being connected to both radios. This, along with AG’s ultra-
high port-to-port isolation help protect your radios from front end damage.
AG in action with SmartSDR @ 4O3A (AG Always on top option engaged)
4.1. Multiple control options
You have five ways to control your AG:
1. FlexRadio over your TCP/IP network; AG will automatically follow two different Slice
band selections and obtain band data from them
2. Manual band switching from the AG Windows app connected via your network
3. Interface Geniustm (IG) connected to your radio(s) via a USB or serial port and connected
to AG via LAN; IG will connect to pretty much any modern radio via its serial or USB CAT
port
4. BCD (Binary-Coded Decimal) signals via the DE-15 VGA-style connector
5. +12 VDC “Pin-to-Port” via the DE-15 VGA-style connector
4.2. SO2R and multi-op with a single FLEX-6000
AG’s extreme port-to-port isolation is perfect for SO2R (Single Operator 2 Radio) contesting with
a single Flex rig! With AG, you can operate SO2R with one radio using a single FLEX-6600 or
FLEX-6700 transceiver in full duplex mode. In other words, the ‘two radios’ in SO2R are both

4O3A Signature – Antenna Genius User Manual

inside your single Flex rig!
GENIUS TIP! All 4O3A Genius Systemtm products use standard TCP/IP protocols to communicate with
each other and with other suitably-equipped devices. The 4O3A Signature team believes in open
standards in ham radio and makes its APIs (library of commands) available freely to other
manufacturers and software authors.

5. HOW IT WORKS
Antenna Genius brings together a powerful CPU, fast network interface, rugged, high power
relays and a programming/control App that runs in all supported versions of Windows. We are
confident AG is the best antenna switch you can buy.
5.1. Tech
AG is powered by a Microchip Technology PIC32 microprocessor, a 32-bit device. Why so much
horsepower in an antenna switch? Advanced technology radios demand high-horsepower
accessories! Also, the extra computing power enables the addition of new features via firmware
updates in the future.
AG has 100BASE-T networking built-in. Based on the Ethernet standard. but ten times faster
than 10BASE-T, it is often referred to as Fast Ethernet. Officially, the 100BASE-T standard is IEEE
802.3u. 100BASE-T devices will also work fine on older 10BASE-T networks albeit at slower
speeds.
5.2. Hardware
AG uses high quality 16 Amp relays rated at 12,800 W DC and conservatively rated for 3,000 W
RF at up to 50 MHz. AG’s relays are used for RF switching and also for the hardware lockout that
prevents two radios from being connected to the same antenna (there is also a software lockout
for redundant protection). The design priority was maximum port-to-port isolation coupled with
power handling ‘headroom’ - twice legal limit at high duty cycle - to enable reliable, long term
operation.
5.3. Software
The AG App runs on all Microsoft-supported versions of Windows and is an integral part of the
AG system. You will use the AG App for initial set up and programming of your AG and also for
alternate antenna selection when you have more than antenna available for a particular band.
The AG App can also serve as your AG control interface if you don’t want automatic band
selection controlled by FlexRadio Slice band changes.
5.4. FlexRadio Ecosystem
In the “FLEX-6000 Signature Series Ecosystem,” the AG App collects frequency and other data
directly from the SmartSDR (SSDR) API, a software-to-software connection performed inside
your PC or over your LAN at very high speed. No RS-232 cables to set up, no “stop bits,” nor
lethargic baud rates. It is a truly modern, intelligent, and high-speed solution.
AG will monitor any two SSDR Slices to determine the bands in use and use this data to select
the appropriate antenna(s) for each Slice.

8. HARDWARE
EXPERT TIP! Read this and the following Software section carefully before changing any DIP switches
or software settings.
8.1. Front panel
Front panel features:
•SO-239 (or N-female) connector for Port A
•SO-239 (or N-female) connector for Port B
•8 SO-239 (or N-female) connectors for antenna inputs
•LEDs: red LEDs indicate which A port antenna has been selected and green LEDs indicate
which B port antenna is selected
8.2. Bottom panel
Bottom panel features:
•LAN: RJ-45 jack connects to your home/shack network (assumes you are using the
network control option as most Flex users will be)
•Two DE-15 VGA-type for users opting for BCD or +12 VDC pin-to-port control in lieu of
network control, these are left unconnected if you are using network control (most
FlexRadio equipped stations won’t use these ports)
•12-15VDC: connect your shack 13.8 VDC power supply here paying attention to proper
polarity, anywhere from 12 to 15 VDC with at least 300 mA will be OK
•OM module: enables connecting the 16 relay Output Module for station automation
•DIP Switches: The side panel has 8 DIP switches for setting the operating mode
configuration.
AG can be controlled four different ways: (1) LAN, (2) BCD, (3) Pin-to-Port, and (4) 4O3A
Interface GeniusTM. The control mode is set independently for Port A (Radio A) and Port B (Radio
B) by the DIP switches. For example, Port A could be controlled over the network and Port B
could be controlled by BCD signals.

4O3A Signature – Antenna Genius User Manual
Index Page 12 of 55
8.3. Top panel
The top panel features:
•A DC power connector for stacking multiple AG units. This enables a single switch to
switching between 16, 24 or 32 antennas.
•Two pairs of dedicated PTT input and output RCA ports for hotswitching protection.
There are independent ports for both A and B radio.
•Red LED for indication that Port A protection is engaged. Green LED for indication that
Port B protection is engaged.
8.4. Where to put it?
Most users will install AG near their station bulkhead, the location where their antenna feed
lines, AC mains, DSL, cable TV, and/or other cables enter the shack and where the single point
ground system nexus is located (you do have a single point ground system, don’t you?). Locating
AG at your bulkhead or other remote location means only three cables need to be run to the
station operating position, coax for the A and B radios and a Cat5e (or higher) Ethernet cable for
the LAN (if not using LAN, you will need a pair of control lines, one for Port A and for Port B).
At the left side is the bulkhead-sited AG @ W0LFA prior to connection of coax lines and ground

4O3A Signature – Antenna Genius User Manual
Index Page 13 of 55
connection:
AG can also be installed at the operating position or outdoors. If the later, install AG in an
outdoor NEMA-rated enclosure and make sure it has a ‘weep hole” at the bottom to allow air
circulation and to let moisture out.
The picture on the right is an AG installed outdoors in very unfriendly conditions (temperatures
down to -28 °C (-17.6 °F) in Minnesota @ W0AD.
EXPERT TIP! Reduce station clutter by mounting your AG near your station cable entrance
“bulkhead.” Slots for such mounting are provided on the top of the AG case.
AG is a 100BASE-T network device using standard TCP/IP protocols, it is therefore subject to the
usual 328-foot (100m) LAN cable run limitations per TIA/EIA 568-5-A. If longer runs are
required, the use of intermediate active hardware such as a repeater or switch will be
necessary. Cat5e cable is recommended, and higher-rated cables such as Cat6 are also OK.
EXPERT TIP! For outdoor UTP (Ethernet) cable runs, be sure to use outdoor-rated cable including
UV-resistance properties if located in direct sunlight.
4O3A Signature encourages all amateur radio operators to employ single point ground systems
for both protection from lightning induced power surges and also for RFI mitigation. A good

4O3A Signature – Antenna Genius User Manual
Index Page 14 of 55
source for information on this topic is the ARRL Handbook, updated annually and available from
the ARRL Bookstore:
https://arrl.org
Another excellent resource for station grounding information and RFI mitigation are several
documents written by Jim Brown, K9YC, available for free download at:
http://www.audiosystemsgroup.com/K9YC/K9YC-old
AG is a computer and thus its electronics will generate some heat. Also, the relays and other
components will generate heat when under load. Make sure there is adequate clearance and
airflow around the AG cabinet sides and top in its installation position.
8.5. DC power connection
Connect a DC power cable from your station 13.8 VDC power supply (anywhere from 12 to 15
VDC is OK, your shack DC power supply is likely 13.8 VDC) to the outlet marked 12-15VDC on
the bottom panel. Center pin is + pole. We recommend using a DC fuse such as those provided
on the popular RIGrunner and similar DC power distribution units (you can use the 1 Amp blade
fuse that comes with RIGrunners). If you don’t have a RIGrunner, we strongly suggest you place
a 1 Amp DC fuse in series with the hot side of your DC power cable.
Make sure your power supply can supply at least 300 mA @ 13.8 VDC. We strongly advise using
a clean, high-quality DC power source for AG and all your other station equipment. Many cheap
switch mode power supplies and “wall warts” are unstable and can generate surprising
amounts of RFI well into the VHF spectrum.
8.6. Network cabling
Most home networks (LAN) operate at Ethernet (10 Mb/s), Fast Ethernet (100 Mb/s) or Gigabit
Ethernet (1000 Mb/s) speeds. All of these networks work fine over Category 5 UTP or better
rated cable such as Cat5e, which is widely available, or Cat6. It’s likely the cable you are already
using for your home network will work great with AG.
If you are unfamiliar with or need a refresher on home networks, a good primer from PC World
is online here:
http://www.pcworld.com/article/196049/the_ultimate_guide_to_home_networking.html
100BASE-T networking has 328-foot (100 m) limitation between active devices (such as Ethernet
switches). Keep this in mind when locating your AG.

4O3A Signature – Antenna Genius User Manual
Index Page 15 of 55
Use a Cat5e, Cat6 or Cat6a UTP cable (not supplied, please don’t use a cheap cable here; poor-
quality high-speed data cables are never a good idea!) between the Ethernet port on your AG
and your station LAN switch or hub (switches preferred over hubs). This should be the same
place where your FLEX-6000 Signature Series radio connects to your LAN. Note this LAN
connection can be as simple as a port on a DSL router or as fancy as a standalone Gigabit switch.
AG can be controlled by PCs connected over WiFi to your LAN as long as AG itself is connected
directly to your LAN via a wired connection to an Ethernet switch or hub (switch recommended;
Ethernet hubs will slow down your LAN).
