Procom 7.5m Transmit/Recieve Whip Antenna for LF,MF and HF Bands SSB
This antenna is intended for transmitting and receiving in the MF-HF range. It is designed for mast mounting with an open feeder installation.
The antenna has very low base capacitance for best efficiency. The power rating of the antenna depends on frequency, but it can very safely be used with 500 W transmitters over the whole MF-HF band.
Installation is easily carried out by means of the two hot galvanized mast clamps. The antenna has very small weight and minimum wind surface, thereby requiring only a minimum of mast strength.
The glass fibre construction gives a stiff and self-supporting structure with extremely good resistance against the corrosive marine environment with UV-radiation, salt, exhaust gases and ice formation as the primary factors.
HF 7500-3 is a maintenance-free and very reliable construction.
