[Elecraft] [OT] Duplexer/Diplexer

[George Pasek]

2 Radios, 2 Antennas, 1 Coax.

That pretty much says it all.  I currently have a KX3 and a 2-meter rig (but I’ll probably be outfitting the KX3 with 2m’s in the future) and I use a HamSticks for HF or a 1/4 wave GP for 2 meters.  Running another coax here is not a option (apartment) so I have been swapping radios/antennas.  Now I’m thinking of using two HF/VHF Duplexers (or Diplexer as they are also called) to join/split the RF.  For example using two of the MFJ-4916S, one port is 1.6-56mHz and the other is 140-540mHz.  Hf power output is limited to the KX3 (12w?) and VHF is currently the IC-2300H at 65w.  I understand that there will be insertion loss/isolation issues.  I have never pursued using splitters on a coax feed before and tho two simple A/B switches (manual or remote) would work better, I’d just like to keep things simple.

>From what I have been reading, the Diplexer route looks like it should work fine given the above?

tnx
