Re: Mounting Low Pass Filter Relays On Bottom of Circuit Board
Already tried that a long time ago - didn't make much, if any difference on my Siglent SSA 3021X spectrum analyzer so not really worth the trouble IMO.toggle quoted messageShow quoted text

Subject: [BITX20] Mounting Low Pass Filter Relays On Bottom of Circuit Board
While replacing the four low pass filter relays with Axicom units, a thought occurred to mount the relays on the bottom side of the circuit board. The bottom side is mostly a ground plane. Wonder if there might be any advantage in isolation of signals ? Have no way of measuring. Perhaps someone with more RF experience can comment.
