We're builded 10 ANT / 2 Radio switch with Gigavac G2SP relays. On each ANT
port are three of them used.
Achieved -60dB isolations on adjacent ANT ports and more than -70dB on non
adjacent ports.
When both radios would like to select the same antenna, isolation is still
around -68dB.
All mentioned isolations was measured at 28MHz.
