What about gain antennas such as the common 1/2 or 5/8 wave?



Assuming this is a mobile install.....

A 1/2w antenna is not a "gain" antenna and requires a high-impedance
feed. A 5/8w also requires some impedance matching at the base, but
its benefits in a mobile installation aren't realized because of the
heavy loading required (a 5/8w at 11m is about 22 feet high!).


Frank;
A 1/2 wave doesn't have gain over a 1/4 wave?



Sure, if it's standing a full 18 feet tall.
