I once put a tribander in a tree for someone who fed it with 75-ohm
hardline of some sort (left over from a big 6m array that had been
in the tree).

At the antenna end, it was a relatively simple matter of moving the
shorting bars out on the driver of the KT-34 a bit.  Other tribanders
may lend themselves to some trick to get up to 75 ohms.

In the shack, 25 years ago one stood a better chance of just feeding
it as-is, but it would be simple to switch different matching sections
with some relays if at the end of the long run one doesn't luck out
& find it looks reasonable.
