I've been trying my hand at building an antenna switch box. So far its working.
But when i have it inline my swr goes up to 1.7 -2.0..
With out it inline the needle barely moves across the 40 channels.
How I've got it constructed is by using a 2x3 plastic project box.
I've used spare parts from old radios for the coax connectors.
And I used a 3 position mode switch from a cobra 142 that i had for parts as well.
The wires used inside are from a piece of coax that i had a length of laying around.
The grounds i have connected to each coax connector but not to the switch and is just a piece of wire i had laying around but not coax.
What I'm trying to figure out is why my swr goes up with it inline.
Could it be the switch or the ground wire that is causing the swr to go up?
