Roy & group:

I have heard of holding a quarter-wavelength of wire next to the HT
while transmitting. This has been called a "tiger tail" and is supposed
to improve you radiated signal.

Some attach this to the bnc at its base - others to the belt clip -
still others just hold it beside the radio as they transmit.

Do you think it might do any good?
