If the inverted "L" is made to be 3/8ths wave long on 160 meters it can
be feed as a 3/4 wave on 80 meters. In this case only a series capacitor
to tune out the TB inductive reactance is needed on 160 meters and a
shorting switch for using the same wire on 80 meters. A large open frame
relay should sufficient unless you are running super QRO.

I have an Inverted-L antenna for 80M & 160M and would like to make or buy a
remote matching system that would work on both ends of both bands that would accept
full power.
I built a system many years ago from a Doug DeMaw, W1FB, article in the May
1985 issue of QST but it has never worked as well as I wanted for whatever
reason.
If anyone is interested, this article can be found at the ARRL QST archives
http://www.arrl.org/arrl-periodicals-archive-search by entering W1FB , 1985,
May, QST.
Anyone have an idea of a matching system that would do all of the above ?
