I'd be a little concerned since the Gigavac GH1 appears to be
rated for MUCH less RF current based on my reading of their
web page compared to the equivalent Kilovac and Jennings units.
Gigavac GH1 3.5 A @ 2.5 MHz 2 A @ 16 MHz 1.5 A @ 32 MHz
Kilovac HC1 14 A @ 2.5 MHz 9 A @ 16 MHz 7 A @ 32 MHz
Jennings RJ1A 14 A @ 2.5 MHz 9 A @ 16 MHz 7 A @ 32 MHz
My experience was that at one time the Kilovac relays, although manufactured
under license to Jennings were not very reliable compared to the
and there was a high percentage of infant mortality.
But then the Kilovac HC1 relay was redesigned and is now much better that the
