Inverted L for 40 & 80 Meters ( end fed )

Maybe an idea for a new aerial ?

End Fed Inverted L for 40 & 80 Meters

Well I had a difficult QSO with a couple of ham enthusiasts up in the North East of England this morning. They were talking on 80 meters and I was struggling to hear them and they were struggling to hear me.

At the moment I am running a 2 element boomless quad for 10 meters, a crude home made vertical for 20 meters and a half size G5RV mounted at 15 feet above the ground. Not ideal for the longer wavelength bands I know but I am working on it.

I have picked up the skeleton of a 4 element 10 meter quad ( cheers Dave M5AFD ) and intend to use it to make a 2 element quad for 20 meters and a 2 element quad for 10 meters ( which my dad can use ). This will reinforce my strengths on the shorter wavelength bands but still leave me wanting on the longer wave length bands.

However, the above diagram could prove the answer. It was kindly sent to me by G0ABY, and previously described to me by David M3MQR. I can utilise the 55ft length of back garden I have available and also the 30ft mast that my quad sits on. The only thing that is holding me back is the length of coax needed ! I also think that a more extensive ground system may be required than the simple earth rod that has been used in the diagram but that will be trial and error when the aerial is up and running.

I have a lot of aerial ideas at the moment but sadly not enough materials or the correct tools at the present. I shall keep my eyes open for some suitable wire going cheap and also some fiberglass poles. Something should turn up soon and then I can get out there and give it a go.

Meanwhile I can still be found most days calling CQ on 28.500. USB. So give me a shout and if you want to arrange a sked then drop me an email via my website http://www.m6jdb.co.uk/
