By the way, for a photo of a UHF UHS pre-amp, or if you're looking to buy one -- assuming this one is working -- there's one on eBay right now... <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=300160564470> It's a UHF "88-split" version. As you can see, it's just a little square-shaped board that installs in the "hole" to the right of the receiver's RCA input connector, if you're looking at the receiver with the helical casting and coils to your left. The RCA connector on it is your new "receiver/antenna input", and the little cable and male RCA goes over to the receiver input. The little red wire in the photo is to get power into it. -- Nate Duehr, WY0X [EMAIL PROTECTED]
