Delta loop home made for 50 mhz

[Jon_Garfio]

I want to share with everyone this antenna that I made past week, tired of no good signals in 6 m band.

The antenna cost  3-4 euros, no more, and I expend about 1 hour to built it.

The antenna in my habitual place.



This is the original idea that I copy to make it.


The item is basically a 6.10cms triangle of wire (I use a 1.5mm but with 1mm is enought).
To tunning the antenna we can use a unun or use a bit of 75 ohms coax (tv coax cable standard), exactly a 99cms for 50 mhz.

This type of antennas have two problems, doesn´t work if have metal parts near and if We mount it at least 1/2 wave leght between the ground, in this case 6m band, minimun 3m between antenna and ground.

First of all, I mounted it into my flat and It was horrible, no rx and a ot of SWR...

I use the antenna without tunner, SWR is 1:1 in all the band, perfect, simple and good performance. All that I can heard, I can worked.




This is the results of my log in two hours.



The delta loop can works vertical or horizontal, if you fit the apex up and corner feed is a vertical polarization.
Here you are the scheme about polarization:

First improvement for the ropes.
