You need a cap is series with the wire....This way you can adjust to
whatever freq. you want.....
Consult an ARRL antenna book or a handbook....Anything within the last 30
years will do....
73 and good luck!

Subject: [TowerTalk] 160 inverted L
>
>Some time ago some kind person NU9S I think put out a number of
>responses about this subject. I am trying to get an inverted L for 160
>going. It is over salt water of the intercoastal waterway. The previous
>posts suggested 130 feet was the best length to start. This goes up 48
>feet on a boat house and the rest horizontal. Fed at the bottom with the
>center conductor of the coax to the antenna and the braid to a 240 foot
>counterpoise at 3 feet above the water along the pier directly below the
>antenna. At 130 feet total it resonated at 1.58 kc. I cut off 3 feet and
>it resonates at 1.6 kc. I cut off 4 more feet and it moved up only to
>1.625. Am now at 122 feet!! Some where I read 127.5 feet was supposed to
>put me at 1.9 kc. . Looks like I will have to cut off alot more
>before I get to 1.9 kc. Am I going in the right direction? Was 130 feet
>too long to start with over salt water? Shall I keep on cutting until
>I get to 1.9kc ? The coax is 350 feet long out there. Any help will
