Notes fo r Using the Antenna
To use your HF-PRO-2-PLUS-T from Komunica® antenna correctly, please read these instructions thoroughly before use and keep
this document on-hand for later reference.
The HF-PRO-2-PLUS-T from Komunica® is intended for use by Radio Amateurs only within their authorised frequency bands. For
use on some amateur bands an antenna tuning unit may be required.
Please note:
1. Thanks to its small size and light weight, this antenna can be used for portable SOTA and Park activations, etc. while still
providing the best performance.
2. The HF-PRO-2-PLUS-T has been designed for use as stationary antenna and is not designed for use on a moving vehicle.
3. To get the best performance from the HF-PRO-2-PLUS-T use of an Antenna Coupler (ATU)is recommended but not mandatory .
4. The HF-PRO-2-PLUS-T should not be installed as a permanent home station antenna as it is not designed to withstand storm
force rain and winds.
5. Do not touch the antenna during transmission as this may cause electric shock or an RF burn.
6. When mounting or detaching the antenna from a base, take care so as not to cause personal injury with the whip.
Desc r iption
1. The HF-PRO-2-PLUS-T is designed to operate on the HF amateur bands between 3,5 and 7-30MHz plus 50MHz.
2. The antenna is tuned to the required operational frequency by adjusting the coil up and down adjustment.
3. To operate on the 3.5 MHz band, installation of the additional coil (N.2) is required between the body of the antenna (N.3) and
telescopic whip (N.1).
4. To operate on 50MHz, simply reduce the telescopic whip element length on top of the retracted N1 body to a length of 131 cm.
5. Thanks to the fibre reinforced polymer (FRP) material with which Komunica® has manufactured the HF-PRO-2-PLUS-T, the
antenna is both lightweight & flexible while also being small when packed so making it easy to carry.
6. To operate on 145 MHz, both the movable coil (N3) and the telescopic rod (N1) are reduced to their minimum length (24cm).
The SWR within this band can be as low as 1.5:1.
ENG

1. When using on a static vehicle: Connect
your Komunica® HF-PRO-2-PLUS-T to a
stable magnetic base of a suitable diameter
(recommended Model: Komunica® TRIPLE-
MAG) or use a solid PL-259 mount,
connected securely. Pre-assemble the
antenna and adjust its length with reference
to the coil settings graph.
2. To be able to adjust to the required length
loosen the locking nut by hand.
3. To select the required frequency band, set
the position of the antenna body N3 over the
scale N4 to coincide with the value shown in
the chart on the right.
4. Lightly tighten the locking ring by hand.
5. For fine tuning on HF, always perform your
TX tests with the lowest RF power possible.
Move the coil up or down until you have fine-
tuned to the desired frequency.
7. Once the tuning is correct, you can already
increase the power, up to respecting the
maximum power of 130W-SSB.
Should the SWR level be higher than
1.5:1 in use on HF, please check your
ground plane or change the location of
your antenna on the car.
Use an Antenna Tuner for maximum
flexibility.
1. When using PL-259 antenna mount (boot
bracket, rail bracket, etc.). Install it where there is a
good ground to the car chassis. If you are not going
to install on a vehicle, remember to use an
appropriate counter poise or radials on the antenna.
2. To install your Komunica® HF-PRO-2-PLUS-T
on the vehicle roof using a magnet, your vehicle roof
will act as an excellent ground.
Position the magnetic mount as close to the center
of the available metal as possible. Should your car
have limited amount of metal in tis roof. You can use
our Komunica® HF-MAG accessory as a ground
plane.
3. If you wish to operate your HF-PRO-2-PLUS-T
on a non-metal surface, remember to use at least
10m of wire as a counterpoise to the antenna.
4. Ideal portable operation is possible using the
Komunica® telescopic tripod (TRIPOD-KIT). It is
very light, compact, and easy and quick to assemble
anywhere. It includes 8 Radial wires that may be
simply laid across the ground and their ends pegged
down.
5. Installation on a balcony metal railing is also
possible as the railing will act as a ground plane. It
is recommended to use an “L” shaped bracket for
such an installation.
This chart is indicative and refers to a standard
adjustment scale that may change depending on
each site and installation method. It offers
indicative measurements only.
To operate at 50MHz, always have element N3
retracted and the telescopic rod (N1) adjusted to
a length of131cm (about-4 of the upper sections
of the telescopic section extended).

Note
Recommendation
HF-PRO-SERIES Accessories:
This wide band antenna can have its
effectiveness reduced due to
propagation conditions.
To provide flexibility it is recommended
to use an antenna tuner with this
antenna.
The HF-PRO-2-PLUS-T has been
manufactured under strict quality
controls, if damage is caused during
shipping, please contact your dealer
promptly.
Design and specifications of this
antenna can be changed at any time
without previous notice.
