UHF MILSATCOM antenna

[merlin]

i built the x-wing antenna and used the winegard lna-200 boost xt rf amp, you get the mast mounted amp plus the bias tee that is powerd by an included 5v wall wart, . this setup has worked for me and has proven to be a reliable way to monitor the 200mhz satcom spectrum , way less expensive that the portable mil spec antennas and easy to build.

I never needed a preamp, even with a cheapo radio like Quansheng UV-K5 8

An acceptable milsatcom antenna can be made with minimal effort and expense. I found the information on YOUTUBE under the username RADIUS.

I checked out the video, not minimal effort and you need a 3-D printer to make some parts.

The plans prcguy created will end up with an antenna that works very well. Mine is still in the attic over a large bit of metal screen and it performs great.

I might add the Monitoring Times/Radio Reference X wing satcom antenna project is designed to sit flat and point straight up having a 360 deg main lobe that favors roughly 20 to 60 degrees elevation with the correct circular polarity. That will pick up all US military UHF satellites that can be heard in the US from anywhere in the continental US without needing to point the antenna at any satellite.

This is just a broad band dipole with linear polarization which will have about 3dB loss receiving a circular pol signal off a UHF milsat. Not much better than using an 11' long whip.
