Model – Alpha DX EMCOMM Antenna
Operating Manual, Version 1.4, August 3, 2020
Overview
The Alpha DX EMCOMM is a 10 to 80 meter capacity hat antenna rated at 250W PEP SSB, 125W CW, or 50W for sporadic
use of digital modes (25W for continuous use of digital modes).
Operation
The DX EMCOMM Antenna an ultra-portable multiband and multipurpose HF antenna that fits in an included Field Bag.
This system requires no moving clips on coils or readjusting of whips for tuning. An integrated leveling bubble enables
precise spatial alignment of all elements, resulting in equal take-off angles. You may also use an external antenna tuner
if your antenna is installed over a poor ground or not placed in a clear area.
Excess RF Exposure Warning
In the United States, the Federal Communications Commission has established guidelines for human exposure to Radio
Frequency (RF) electromagnetic fields. The commission’s requirements are detailed in parts 1 & 2 of the FCC’s rules and
regulations {47 CFR, 1.1307(b), 1.1310, 22.1091, 2.1093}. It is the responsibility of the owner/operator of this device to
follow all applicable warnings and precautions regarding human exposure to RF fields. Additional references:

Assembly
A) Locate then assemble the Alpha
Match and Tripod: Screw the Alpha
Match onto the Tripod (A), taking care
not to cross-thread either one.
B) Locate and install the four black 26
inch MilStick elements, and screw each
hex nut onto the bolts (B).
C) Locate the 12 foot Counterpoise
wire & secure the ring connector over
the bolt (C) with the loose hex nut.
C.1) Proper placement of 12 foot
Counterpoise is so that it is run above
one of the tripod legs, otherwise the
system will tip over. This is a
Counterpoise, so please ensure this
wire slopes away from the antenna and
isn’t laid on the ground, before staked.
C.2) Extend the Counterpoise and
place the stake into the ground. The
Counterpoise enhances a DX pattern in
the direction it is run, and an NVIS
pattern in the opposite direction.
D) Locate and install the one black 26
inch MilStick element, to the top bolt
of the Alpha Match (D to D).
E) Extend the Legs (E) on the Tripod,
and secure each with the locking
mechanism.
F) Rotate the Crank (F) till the mast is
fully extended & tighten the set screw.
G) Connect your coax to your
equipment first and then to the SO239
ensuring that the coax does not coil up
on itself or touch the elements.
OPTIONAL GUYING: At the users
discretion, user supplied guy ropes can
be placed at the base of the extended
mast (Ref. ‘F‘).
