The Inverted L antenna has all kinds of possibilities. We recently covered the Reverse Fed Grounded L Antenna. Here we look at a simple method of adding two extra bands. It's a great opportunity to experiment in a small garden and work some DX. Presented by Peter Waters G3OJV.

    Done this with a QRP radio and a Christmas tree light gutter clip- angled a steel washing line and talked to Slovenia. Fair play Peter

    Use 1/2 horizontal, plus a 2nd 1/4 at the far end. HeyPresto! I call it "open quad". (QRP CW!)

    Many thanks again Peter for a great video, please don't forget the second part of your last show on the JPC 12 antenna 73 Martin G7UGB

    Thank you, Peter. I need to play with an inverted L antenna. 73, KF0NNQ.

    Your channel inspired me to get my technician license TY. I'm about to start building antennas and plan on starting with a resonant dipole. Since I only have 10m for HF the inverted L is very attractive. I have a question though. Is higher always better for antenna placement? I don't understand angle of radiation principles yet but figure it would probably be better to get it as high as possible especially because I am in a mountainous region. If I'm wrong please let me know. God bless from your friend across the pond šŸ¤

    Very interesting video Peter and yes a great ant for the low bands. I once put a 40m trap on the top of my 40m vertical, then added extra wire, and got a 40/80 inv L, which worked extremely well. My top section was actually sloping down, but it seemed to fire better in the opposite direction. Happy Easter to you and your family. Zl3xdj.

    I've used inverted L for years feeding from ground. First an trap L with unadillatraps for 40 and 80m so it would work on 160-80 and 40m. Even at 6m height I worked DX on 160. Eventually burned the traps and now using 8010 EFHW with 49:1 UNUN at 11m height. Work very well. The beauty is that I can feed the wire without the UNUN , but with proper groundsystem and use it on 160 and 60meter. BTW.. I seem to remember a rule to inverted L that the vetical section should be more than 1/5 of total lenght. Any toughts on this Peter?
  • @geoffaddis1075
    Have you tried an end fed. dipole in an inverted L configuration with the unun at the base of the vertical section?

    Should you choke the coax at the feedpoint of the 49:1 transformer? I know the 49:1 Balun I have, the coax does radiate somewhat. Robert KD4YDC
