2 meter halo loop

Post by MW6ZAN »

Hi all im going to be running 2 meters ssb over the summer and will be building a 4 element 2 meter yagi i have noted in my june issue of radcom adverts for 2 meter halo loops at a very good price im wondering if a halo loop would have an advantage over the 4 element beam any thoughts. 73

Personally for DX on 2m I'd be looking at at least an 8 element, probably 11 element beam, 4 ele will give you about an S point gain over a horizontal dipole.

What e said, an t' halo will be the same as t' dipole in terms of gain
Dont worry what class of licence he holds, worry what class of bias he applies to the amplifier !

I think the Halo will be down on the dipole as the halo spreads its radiation over a greater arc. I think. Feels right....

As someone who does ssb on V/UHF and used a halo, I would agree with you Andy, negative gain against a dipole.
If MW6ZAN is after an omni I would suggest a cloverleaf, the Wimo "Big Wheel". Beats a halo into a cocked hat.
The main reason for a horizontal omni is as a "sniffer" aerial. Against a 4 ele there will not be much advantage as the yagi will have a wide "nose"
Build the 4 ele, do NOT scrimp on coax (RG213 the ABSOLUTE minimum) and listen on the first Tuesday of the month between 2000 and 2230 local time

Those halo antennas are all cornbread and chicken to me, I find dipoles seem to do better
