Hi Guys, I'm trying to set up a 160-m. Inverted L for ARRL-160 this weekend but am having an interesting tuning problem. All thoughts appreciated! The Inverted L is made up of #12 stranded copper wir
I would not connect it to the tower, itself. If the tower is connected to the ground rods, then I would just use radial wires laying on the ground. I would lay more ground wires if using just those.
Hi Dick You can get some screwy readings if there is a BC station nearby. I can't even use my analyzer here on my 160 inverted L because of RF from the local. I have to use the SWR bridge in the shac
The issue with teh AM BC Strong Signal interference is addressed in the Nov/DEC NCJ ( National Contest Journal ) magazine article ..and article uses exact same antenna analyzer as Dick is using ! 73,
Rick My inv-L is 60' vertical plus 75' +/- sloping down and away from the tower (70' topped with an X7). There is 6' separation between the tower and vertical wire. I also use the tower as a folded m

The coax shield should be going to the radial system. Earth is NOT a good return for antenna currents/fields. You don't want/need an EARTH connection. You DO need radials. The antenna is electrically
Isn't it about time to split off an "All Inverted L's, All the Time", e-mail group? Same questions, same 100 answers each as the last 100 times. 73, Terry N6RY _______________________________________
Helped a friend set up a 160 meter antenna. He was 2 miles from the AM station and even the meters in the shack couldn't be trusted, let alone the MFJ analyzer. A ICE BC filter cleared everything up.
This is a great article on dealing with practical problems in measurement and matching. Thanks for making it available, Jay. The use of a hairpin match is, by far, my favorite method of matching impe
