HF 7500-3

7.5 m Self-Supporting HF Transmitting Antenna for Mast

Mounting

DESCRIPTION

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.
