I use a variety of couplers, I have a multitude of 49:1 and the odd 4:1, these match the impedance of the antenna to the feed line. I then use a tuner to make the PA finals completely happy. This last step is not truly required, but it stops any worry

It all takes time m8. We start off with big big plans but then at some point they start to change slightly lol. Off to do a bit in the new shack.

I really do want to see how it works for you. I'll probably put up a low linearly loaded dipole sitting above my radial 'field' to enhance vertical take off.
Compromise is necessary. I used to have a 4 x 17 ele 144MHZ array with an 3CX800 amp and run moonbounce - then I moved and I've never been able to set anything like it up again. Vertical wires, halo's & moxons all fed by coax are doable here. It's not even worth trying eme or even VHF from here as I'm in a fairly steep sided river valley a matter of tens of feet above sea level - the river is tidal. I never see the moon at a decent declination.
I'll get something sorted other than a 1/4 wave vertical and we should be able to chat easily

Wayne I was surprised how much water got in a plastic bag i use in the same way. Looking good m8 all i managed today was the coax from the cobweb fed into the new shack. Might get the main pc over tomorrow and a radio will have to come with that lol.

Looking good Wayne. I have only managed to get one coax in so far.
