I have a Tram 1410 Discone up about 20' or so. I purchased an OmniX as an upgrade about a month ago with high expectations, based on reviews posted here. I must say, I noticed slightly degraded performance, so I put the discone back up for now. Either one is a tremendous upgrade to the stock antennas, however.
Using a Stridsberg 4 port MC to a BCD536HP, 2 BCD996P2 and various SDRs for experimenting.
