Thats the reason why you need a beam and preamp, or a dish with a LNA. And you want us to believe a consumer grade RS handheld can do this feat with just a rubber duck??????? Come on. It is definetely possible, BTDT. Why should there any difference to my satellite handheld phone, which also works just with some flimsy antenna?! -------------------------------------------------------------------------- Years ago I bought a Drake TR 270 to do amateur sat. work. (2mtr. uplink and 440 downlink) when I figured out that I was going to have to get for an antenna and possibly a dual rotor setup to track the sat. I dropped the idea. I think at that time you needed a beam with about 12db of gain for it to work reliably. That translates into about a 14-15 element dual polarized beam. That is one big antenna. Plus any mil-sat equipment Ive ever seen invariably use the little mini dish's to use in conjunction with it. Thats where I got the idea. I guess things have changed. I know the signals that come down from space are extremely low power,, with the possible exception to ISS, I think they may be beaming their signals to earth and running at a higher power so people can pick them up easily. A geo-synchronous sat. at 25,000 miles out running on 40-50 watts isnt much power. The OP gave me some freqs. to try on my VR 5K and Im going to give it a shot and see what I come up with.. I guess I had a case of "open mouth and insert foot" J |
