A COLLECTION OF MURA SWR/ANTENNA TUNER METERS VINTAGE NEW OLD STOCK. ———— VERY RARE ————-
Video Rating: 0 / 5
The making of my single element Delta Loop antenna. Designed for 11m but can be used on 10 which is what I built it for originally but it works on 20m and even down to 80m although obviously a good antenna tuner is required. Ideal for short spaces. I was going to build this for 20m but the length of the rods would have made it dearer than I wanted to pay. This project was to come in under budget at £25. Full build details on www.open-channel.co.uk

Made this in a few hours, and it is FAR superior to any of the antennas used in the past. Put against GP, HLLY, and Commet 5/8 wave, and has lower swr’s across the whole band. The other one is for 2 meter. It is also homebrew. It works better than all the others I used. (It’s modified too)

I decided to resurrect my vintage Avanti Sigma 5/8 Wave CB antenna which was stored in various places around the house. After cleaning the loading coil and connections I installed it temporarily on the fence for testing. SWRs are flat on channel 0 (26.955mhz one 10kc channel) below regular channel 1. SWR readings on channel 40 are 1.7 :1
