I have been working on some delta loops for the PMR Band and 70 cms
Delta loop :
Finished Antenna for the 70 cms band,
To be sent for my friend to try in Brighton very soon.
Even so it as a good low VSWR over the frequencies. with a low angle of 25 Deg of RF.
For thoes who would like to make their own.
Here is the info.
The Equation should be fine for the 70 cms
and pmr band.
I used Brass wire of 1.5mm dia and mounted on the 3 D printed Delta Loop mount.
The Blue Chart Gives a Calculated length
for the frequency of the 446 MHz Band. Also the 470 MHz Ausi CB uhf Band.
Brass Wire can be bought from
Inverted V Mount For 446 Band
This Mount was all connected together with 50R coax and a Choke with a short run of Cable and gave a good vswr reading of
1.11:1 on my VNA.
Been Busy once again working on a two Band Dipole.
Also been making a 3D Mount for this antenna, 2 in one and hoping to post pics when ready to do so.
The Delta Loop is now on sale on EBAY in a kit form with a new mount.
