The pictures tell's the story. :mrgreen:
On the radio side we use any 50 Ω coax
Remember the antenna side we need ¼ Ψ coax or a multiple there of for the specific
bands, otherwise all efforts are in vain.
Brew, brew, brew....then chew :twisted:

on VHF/UHF we make a cross yagi - vertical and horizontal selectable and then if you add a 1/4 or 3/4 wave cable to the one or other you create left hand or right hand polarization using a relay setup such as above

same with vertical antennas make it directional by adding lengths of cable or taking away etc

yes interesting topic Johan

we forget about relays sometimes
