80m Loop

I have completed the install of the antenna. If I had to to this over again I do not think I would have pre-strung with rope. It would have been simpler to just pull the wire!

The following photographs show some of the steps.

WA1FFL LADDER-LOC

I am using the WA1FFL to manage the feed point of the antenna. This allows me to support the feed-line along with the antenna at this point. Construction details below!

Following the instructions for the Ladder-LOC, I cut the webbing 7/8’s of an inch above the window and test fit the wiring. It is suggested to caulk the top of the joint to prevent water from entering. A little silicon caulk fits the bill. Let this cure!

I have started getting the antenna in the trees. Four of the support points have ropes in them. Today we put a pull line through the 5 trees that support the antenna. We used a combination of a slingshot with a fishing reel and an Arborists throw system. Tomorrow I will measure the FLEXWEAVE FW-14P wire and pull it through the supports. Here are a couple of pictures of the setup.

The loop antenna is hung in six trees around my house. One tree supports feedpoint ladder-loc, the rest hold the antenna wire.

I am building a horizontal loop antenna for my home station. The antenna is designed to be resonant at 80m and is fed with 450 ohm ladder line to an LDG RBA-4:1 Balun and tuned by an LDG RC-100 remote tuner. This combination should accommodate operation on multiple bands above 80m and is less susceptible to man-made noise. For this build I am using Davis RF FLEX-WEAVE insulated antenna wire for flexibility and longevity. I also purchased factory built coax lines for this antenna. I am using Low Loss flexible RG-8x cable.
