The HF-PRO-2 antenna works on short wave according to the principle of a shortened Lambda-VIertel radiator, on 6m as a full length L/4 radiator. The antenna body is formed by a coil, the outer shell is movable and has a tap for the coil. This makes it very easy to set different coil values depending on the frequency. A precise scale on the coil body helps with the setting. In addition, the length of the upper radiator is changed for precise tuning.
The connection is a solid PL connector, for operation the antenna is placed on an appropriate holder. Like any vertical antenna, the HF-PRO-2 needs a good counterweight. Maximum transmit power 130 watts SSB.
The HF-PRO-2 from Komunica Power is an excellent antenna for hiking or a holiday with small luggage. It covers the most important shortwave bands: from the popular 40m band all shortwave bands up to and including 6m. All of them for shortwave and the "Magic Band" 6m. The HF-PRO-2 is tuned to a new frequency in seconds by moving the coil tap. Fine tuning is done with the radiator above. Usually a SWR of 1:1.5 can be achieved, depending on the set-up location and counterweight. A base is needed for operation, for example a magnetic base for the car, or a clamp for the tailgate of the car. Please note that the HF-PRO-2 is not intended for use while driving. When stationary, it can be set up on a balcony railing with a magnetic base that also serves as a counterweight. If no metal counterweight is available, a wire of approx. 10m length should be used as a counterweight.
