Have a question for those that have extended RF remote antennas. In the past, I usually just use one or more satellite antennas connected by coax through a splitter, and then amped with about 10db. Works fine over great distances. Problem is the new A65's have a 3 connection stereo type mini connector, unlike the the 2 wire types of older ones. Has anyone taken one of the new ones apart? Is the tip & ring the only actual antenna connections, with the sleeve being just a ground at the device?
Thanks
Dan

Well, have some news.
Jumped right in and played around with these critters. The antenna has a small preamp built in. You can also run these out for a ways. Extended it with shielded stereo mini-jack cable about 50ft, worked fine. And since I was integrating two B65's, ran into some other fun stuff. The office where these were at had a lot of steel, so there were dead spots at the opposite ends. If I used one antenna, and split the output between the two B65's, it worked fine in the middle areas, but could not find the sweet spot where the entireoffice was covered. Trying to fudge two antennas into the mix, however, one at each end of the office for better coverage, failed. I could get either antenna to work both B65's, but not together. It could've been from impedance mismatch, or not enough power to drive both preamps, or....? In any case, no amount of fooling around with positions would get them to work together. If Sony would give out more specs, or better still, make a little adapter to mix signals and keep power high enough for them to work..... Yeah, and I might win the lotto, too.....

Be careful with the extensions. Sony uses roughly a 50 Ohm impedence on their antennas, so using a 75 Ohm cable to extend with is not necessarily going to yeild a satisfactory result.

Good luck!
