Water Pipe T-Joint at VHF Antennas








By the way, I was (and may be am) not an experienced VHF- man before I decided to do my VHF YAGI. I had serous doubt that I spoiled lots stuff while I made my YAGI. So I found for solution how to do the antenna without turning in garbage my antenna's material. When I went around a house-ware store I have seen polystyrene water pipe T-joint. Picture 1 shows the T- joint.

I have bought some these ones. While making the VHF antenna several of T-joints spoiled were spoiled but other ones worked well in my design. Picture 2 shows T- joint installed at my antenna.


The design has some benefits:


1. Antenna elements are isolated from traverse with gap in 6-10 mm


2. It is possible to move the antenna elements along the traverse.


3. It is possible to play with antenna design- change length between antennas elements and easy to change the elements
