Terry and Juergen,

Many thanks for your replies. I have done some research and believe that is what I need?

A remote tuner is not going to happen but will this help? And is it best to install it near the antenna or transceiver? It says this is suitable for ‘short coax cable runs’. I have a 19m (62’) Ultraflex 7 coax run. Is this considered short?

NO

I make my own and a good reference site is here https://www.dj0ip.de/rf-cmc-chokes/diff ... of-chokes/

NOTE: The toroid core type is very important so make sure that you buy the correct one 240:43 for 80 through 30m and 240:31 for 30m through 10m

See http://www.karinya.net/g3txq/chokes/ for details about Toroid and frequencies

I use RG58 coax which is fine for all HF frequencies if you keep the pigtails short

This is the design that I use
