![]() "Theplanters95" wrote in message ... Have you tried an halo or loop antenna? M2 Antenna's and Par Electronics makes them. Homebrew plans are on the net. The halo is a 1/2 wave dipole bent into a circle. Common designs use 1 turn, but 3 turn halo's have been used, with more gain. Stacking 2 halo's also provide additional gain. Weak signal operaters on VHF and UHF use them mobile on a regular basis. Randy ka4nma Two points of clarification. The PAR design is not a half wave antenna. It is longer than a half wave- that length combined with the isosceles triangle shape yields an excellent omni pattern and a bit more BW The 3 loop haloes were not 3 turns. The loops were configured as a folded dipole in order to increase the inherently low feedpoint R (10-15 Ohms) of a single loop. There is no increase in gain from doing this. Dale W4OP |

Hi Dale,
Are you saying that the old saturn halo was not 3 loops? It sure looks like it in the pictures that I have seen. I know that your design (the Par Omniangle) is not the classic 1/2 wave halo, and does offer more advantages over a halo. I sure wish I had a 2m and 6m for the upcoming VHF contest. Randy ka4nma |
