Source for L-Band Preamplifier and Bias Tee?
by Eric A. Cottrell 12 Jul '07

12 Jul '07

Hello, I am looking for a Low Noise Preamplifier for L Band and a Bias Tee. Down East Microwave seems to be closed for the summer. I was looking at one of their 1296 MHz Preamps and wonder if it could work outside the band, like at 1090 MHz. I got a 1569 MHz preamplifier for GOES but do not have a Bias Tee to try it. The ones I saw were either for up to 1 GHz, or for up to 40+ GHz ($$$). I got a WinRadio WR-LNA-1500 at Dayton but I did not get a chance to really try it. The WR-LNA-1500 managed to fry two of my receiver's front-ends then destroyed itself when I ran it off of vehicle power. This was before I realized what was going on. The US WinRadio Service Center is checking with Australia HQ to see if they fix that model. So I would rather not buy the Winradio Bias Tee just in case there are more problems. Are there any surplus places that sell Bias Tees? I can deal with SMA connectors. I tried searching for kits or construction articles for preamplifiers but only found some stuff overseas. Do I have to wait for DEM to reopen? 73 Eric

Bias Tees
by Jim Jerzycke 11 Jul '07

11 Jul '07

Hello, all I have a small quantity of AVCOM DCP-66 Bias Tees (power inserters) that are rated from 25~1500MHz. Solid aluminum block with a feedthrough cap and ground post for DC. Most of them have female "F" connectors on the input and output, but I changed a few of them to female "TNC". These were surplus from an Earth Station I helped rebuild, and were used to send DC up the coax to commercial LNB's with a 950~1450MHz output. I use one to power my S-Band downconverter, and it works fine. $25 each, shipping included. Contact me off-list if interested. 73, Jim KQ6EA
