Note that you will almost certainly need an antenna amplifier too (unless you make a huge antenna ;) Even a specialized receiver needs one to compensate for the cable loss. And the ezcap receiver is not too sensitive either... As Marcus stated, many use QFH antennas (sometimes called QHA), though many also use turnstiles (two, crossed dipoles) because it looks easier to build. If interested, there's some info you might find interesting on my site: http://www.jcoppens.com/ant/qfh/index.en.php (QFH antenna construction) http://www.jcoppens.com/sat/gaasfet/index.en.php (Example antenna amp) John _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
