 2m Big Wheel  70cm Big Wheel |
The "Big Wheel" is a horizontal
polarized omni directional antenna. Usually
highly directional antennas are used on VHF and
UHF, which have the capability to bundle the
radiated energy in one direction and eliminate
interferences from unwanted directions. But
these effects are not always welcome. With
directional antennas it is nearly impossible to
monitor a frequency for signals from any
direction. Usually the directional antenna stays
in the direction where the most signals are
expected from and some rare contact in an other
direction is lost. In such cases the Big Wheel
is an ideal antenna which should be used
together with a directional antenna. Big Wheel antennas by WiMo are made of stainless aluminum, all other hardware is made of stainless steel. The antenna gain is approx. 3dBD, each Big Wheel has a N-jack (female). By vertical stacking of two Big Wheels you get a gain of approx. 5dBD. To connect two antennas to one coax feed a usual phasing harness can be used.  6m Big Wheel |

To achieve a higher gain, Big Wheel antennas can be stocked vertically. With such a configuration either 2, 4 or 8 antennas are used. The antennas are connected with 2 (4,8) cables of exactly the same length to a 2-way (4-way, 8-way) power splitter. This solution is also suitable for higher power levels (> 100W).
Alternatively and more affordable are our phasing harnesses for crossed yagis. You can use article no. 18046 (for 2m) or 8048 (for 70cm), cut the two cables to the same length and attach N connectors. This solution is suitable for power levels up to 100W.
