those powered antennas are less than medeocre. You boost the signal, ALONG with the noise!
If your willing to shell out the cash, for 100 bucks you can get the Magnum Dynalab ST2 antnenna. Its supposed to be pretty good. I have been wanting to get one for my Sansui 517 tuner for a while but i just cant break down and spend 100 bucks on an antenna.
I use the T wire one now but it doesnt pull in anything from the other islands, when i know radio's in some peoples truck will. etc.
