1. Before the installation.
1.1. Selecting the Antenna Installation Site.
The WaveHunterTM consists of a cluster of Poynting Antenna’s patented, wide-band Uni-
Directional Antennas which together creates a 360º electromagnetic radiation pattern. A
‘Radiation Pattern’ defines an Antenna’s ability to efficiently transmit- or receive radio signals
within the three-dimensional area defined by this ‘Radiation Pattern’. (see ‘Radiation Patterns’ in
the Technical Documentation of the WaveHunterTM).
An ideal omnidirectional Antenna has, as close as possible, a 360º clear view towards the
horizon. This implies that the Antenna installation site must have as little as possible solid
obstacles in the line-of-sight of the Antenna System, 360º in the horizontal plane, towards the
horizon.
Any substantial structures in the path between the WaveHunterTM and the shore based towers it
is pointing to will cause degradation of the signal. The location of the WaveHunterTM should be
chosen to minimize blockage caused by the structures of the ship.
It is desirable to be mounted high enough to minimize the effects of the surrounding structures.
Large, solid, structures will cause significant signal loss while wire rope stays, lifelines, small
diameter handrails and other accessories may cause little to no noticeable loss.
1.1.1. Horizontal Radiation Pattern (or Azimuth) - The WaveHunterTM has an excellent Horizontal,
also known as ‘Azimuth’, radiation pattern that will ensure perfect reception from 360º around
the vessel provided the area ‘around’ the Antenna System is clear of obstacles.
1.1.2. Vertical Radiation Pattern (or Vertical Aperture) - Equal consideration should be given to the
vertical plane. The WaveHunterTM Antennas have an approximate 60º vertical aperture at the
lower frequencies; approximately 30º below the ‘horizon’ and 30º above the ‘horizon’. the
‘horizon’ being the 0º ‘line-of-sight’ of the Antenna pointing to the horizon. The ‘aperture’ of
the Antennas should be unobstructed as far as possible.
This ‘vertical aperture’ is important to counteract any ‘Pitch-and Roll’ of the vessel
that would result in loss of transmission- or reception of the signal.
1.1.3. Obstacles - Solid objects are objects such as Masts, Exhaust Funnels, other Antennas, and
such like, mainly metal structures, that can potentially attenuate the Radio Signal being
transmitted from- or received by the WaveHunterTM.
1.1.4. Close proximity to RADAR - Do not install the Antenna near the ship’s RADAR, especially on
the same horizontal plane. The electromagnetic pulsed energy from the RADAR may
significantly adversely affect the Signal-to-Noise (SNR) of the internal Routers’ receivers
installed in the WaveHunterTM.
It is recommended to position the Antenna at least 4 feet (1.2 m) above or below the level of
the RADAR Antenna and minimum of 15 feet (4.6 m) away from the high power short wave
radars.
The S-Band RADAR, in particular, operates at frequencies between 2,9 – 3,1 GHz and, since
the WaveHunterTM is designed to be a wide bandwidth Antenna, to be able to receive signals
in the frequency bands 617 MHz – 4 200 MHz, SNR protection for the above S-Band
frequencies can only be offered by the filters in the Router’s transceiver. It is therefore

Page 6 of 31
www.poynting.tech
Poynting Group (Pty) Ltd
Registration Number: 2014/239013/07
prudent to provide as much physical separation as possible between the radiation envelope
of the RADAR and that of the WaveHunterTM.
RADAR blanking Since RADAR provides ‘situational awareness in the direction of the Bow
and +175° from 0° (the ‘bow’) towards the Port- and the Starboard side, there can be approx.
10° ‘blanked out’ or ‘exclusion zone’ towards the stern. This means that placing the
WaveHunter towards the Stern is achievable without fear of RADAR interference.
1.1.5. Rigid Mounting Position - The mounting platform should be rigid enough and not be
subjected to excessive vibration. The movement of the Antenna can be minimized by
installing at the centre of the vessel. If these conditions can be only partially satisfied, find the
best compromised installation site between the various considerations.
1.1.6. Ideal Height of Installation - Since the Router/s installed in the WaveHunterTM will be
communicating with shore-based telecommunication towers, it would be advantageous to
install the WaveHunterTM as high as possible on the Vessel relative to the waterline. Typical
positions will be on a spreader, +4 feet (1.2m) above the RADAR dome.
If both X-Band and C-Band RADAR systems are installed it would typically be worthwhile to
install above the X-Band RADAR which. in most cases, will be mounted higher as it is the
smaller of S-Band and X-Band RADAR Antennas.
1.2. Recommended size of the pedestal
Please refer to the drawings in this document. The WaveHunterTM can be supplied with and
installed on a pedestal or without, refer to Pages 20 and 21 of this document.
1.3. Safe Access from Radiation Hazard
1.3.1. Passive System - The WaveHunterTM Antenna System is a system of passive elements
capable of radiating Electromagnetic Wave in designed Frequency Bands and as such the
System itself does not produce radiation that can be dangerous to any lifeform.
1.3.2. Effective Isotropic Radiated Power (EIRP). Antennas are designed to concentrate the
Electromagnetic Wave in a particular direction either Omni-Directionally or Uni-Directionally as
mentioned above. Antennas increases the ‘concentration’ of Electromagnetic Radiation that
potentially the Human Cells would be exposed to.
Although this is taken into consideration when the maximum RF Power output of a Router is
specified in the FCC (Federal Communications Commission) Specifications, it is
recommended that ‘Radiation Warning Signs’ be placed in strategic locations when there is a
possibility that personnel or passengers on a vessel could come into close contact with the
WavhunterTM Antenna System.
1.3.3. Router Transmitter Radio Frequency Output Power - LTE, 4G, 5G Routers’ specifications are
governed by regulations promulgated by various standards bodies in various Countries like
the FCC mainly in the USA, limiting the RF output power from the transmitter. Many of the
standards adopted around the World take their input from the FCC.
In this instance we are concerned with the RF Power output of the Router/s transmitter/s
installed in the WaveHunterTM. Radio Frequencies in the range 3kHz – 300 GHz are regarded
as the ‘Radio Frequency Spectrum’. The main safety concern, as far as RF radiated Power is
concerned, is to protect people from being exposed to too high levels of Electromagnetic
(Radio) Waves that could cause damage to cells within their bodies and lead to illness due to
this radiation.

All Routers installed in the WaveHunterTM should conform to international standards limiting
the RF radiation presented to the WaveHunterTM Antennas. Although there are many
parameters governing the level of Electromagnetic radiation allowed to be transmitted from a
LTE/4G/5G Router, class 3 devices (most Routers) are limited to 23dBm or around 200mW
and some Class 3 Routers are allowed 26dBm at higher frequencies i.e. approximately
400mW. The integrator/installer need not necessarily be concerned with these numbers as
the main concern is to only install Routers passed by the various standards bodies, mainly the
FCC.
1.3.4. Mounting position promotes safety – Apart from the Router transmission power being
restricted by the abovementioned regulations, since the suggestion is to mount the
WaveHunterTM as high as possible, away from structures that can impede the transmission
and reception of radio signals this will promote safety as well since personnel or passengers
on the vessel would not normally be in close proximity of the installation and be in danger of
exposure to the electromagnetic waves from the installed Router’s transmitters radiated
through the Directional Antennas inside the WaveHunterTM Antenna System.
The following Website from the FCC provides more information:
https://www.fcc.gov/engineering-technology/electromagnetic-compatibility-division/radio-
frequency-safety/faq/rf-safety#Q2
1.3.5. High performance System - Whilst the above recommendations are set out to ensure optimal
performance and cares which should be taken in positioning the WaveHunterTM, the patented
Directional Antennas, configured to provide an Omni-Directional pattern for MIMO enabled
Routers, will provide excellent reception of land-based LTE, 4G and 5G Signals and although
we urge good positioning, we have found the system to outperform any other Antenna we
have tested.
