[TenTec] Orion antenna isolation measurement

[John Buck <kh7t@arrl.net>]

On my Orion, I measured the following isolation between antenna ports 1 
and 2.
I fed Antenna port 1 with an HP generator with a calibrated attenuator.
I set the signal at S9.
Then I switched to Antenna 2 and increased the signal level until I got 
S9 again
28.5 MHz, 40 db,  Antenna 2 open
3.888 MHz, 45 db, Antenna 2 open
3.888 MHz, 50 db, Antenna 2 terminated with 50 ohms
