Halo Antenna 2M-- From N2KBK Halo Antenna 2M Square -- From N4UJW Halo Antenna 6M -- From W3DHJ HenTenna -- From The N4UJW Antenna Design Lab ... 9 dB, 70cm, Collinear Antenna From Coax -- Version I -- From N1HFX 2M/440 MHz Dual Band Copper J-Pole From N7QVC 432 8 Element Quagi Antenna By N2KBK. In looking on the I-Net, I did find a company that made a small tubing, round 6m, 2m, 70cm halo's (separate) and the 6 meter one had a support coming off the mast and to the open end of the antenna for support. The antenna was then raised above ground for some initial testing. The antenna being tested in the garden. SWR was good straight from ....

SHARMAN HLP 270 DUAL BAND HALO LOOP ANTENNA 2M 144 70cm 400 - 470 MHz ABOUT SHARMAN HLP-270 - DUAL BAND HALO LOOP ANTENNA Super Light-weight Half Wave Dipole Square Loop Antenna. Features / Specifications: High gain, mounted horizontally Frequency: 140 - 150/ 400 - 470 MHz Gain: 4 dB(VHF) / 5 dB(UHF) VSWR: ≦1.5 Max. Po.

The big-wheel, also known as a clover leaf because of its shape, consists of 3 full wave loops fed in parallel. Although bigger than the previous 2 omnidirectional antennas, a single big wheel has a gain of roughly 2-3dBd. Phasing 2 big wheels mounted one above the other will result in a gain (in the horizontal plane) of about 5dBd. Each dipole performed under 1.5:1 SWR from 142 to 158 MHz. I used RG59 cable for the dipole to Tee connectors, then LMR400-75 for the TEE to TEE phasing. After mounting the array to the side of the tower, performance is still very good. 1.5:1 from about 140 MHz to 156 MHz with a 75' run of LMR400 up the tower.
