What is a Tiger Tail on a handie talkie antenna ?? Just curious. My Diamond SRH77 is just about usless on 2 meters. I hope that I can return it.
A tiger tail is quite literally a counterpoise. The problem is that the same current must flow on both halves of your antenna system. Whether your antenna is a dipole or a quarter wave ground plane there are two halves to every antenna.
On an HT, the other half of your antenna is your HT metal chassis and it's coupling with you holding it. It makes for a not very effective other half. The tiger tail provides a tuned other half and that increases current flow on the radiating element, the HT antenna.
The difference can be surprising and I generally leave one attached to my HT all the time. I use RG-174 and just connect the braid to the ring connector. This gives me a supple and quite wiggly 'Tiger Tail' that doesn't get caught on things or get in the way. Stiff wire can be used but it's inconvenient a lot of the time.
