Europa-List: Re: toroids for vhf comms aerial cable

Hi again,

I forgot to mention that you SHOULD NOT use a balun for VHF antenna construction
as suggested by "Martymason". I have been advised that the balun will pass all
the transmit energy to and from the entire length of the co-axial cable. This
is what you DONT want from a transmit antenna and can damage your radio. 

Baluns are used for receive antennas e.g. VOR antennas.

Bye all

Tony
