You can also make a somewhat directional antenna by using a bent dipole configuration.
You can confirm which element is connected to the center conductor by temporarily removing the black lid on the dipole base (it can be easily pried off with a nail or flat head screwdriver). If you mismatch verticalRHCP, verticalLHCP, horizontalRHCP, horizontalLHCP youll only get a 3dB loss. This is essentially the orientation of a signal, and an antenna with the same polarization should be used too for best performance.Ī dipole can be used in either vertical or horizontal polarization, just by orienting it either vertically or horizontally. Then place the suction cup on the cleaned surface and close the lever to activate the suction.
To use first clean the surface with window cleaner or isopropyl alcohol.
The legs of the tripod are bendy and rubberized so can wrap securely around many objects. a pole, tree branch, desk, door, window sill. This piece allows you to mount the dipole on a variety of different locations.Į.g. These smaller antennas cover UHF to 1090 MHz ADS-B, and even still work decently up to L-band 1.5 GHz frequencies. The telescopic dipoles are detachable from the dipole base via a M5 thread which allows for greater portability and the ability to swap them out. This coax cable extension allows you to mount the antennas in a place that gets better reception. On the inside of the base the two dipole element sides are connected with a 100 kOhm resistor to help bleed off any static.
This helps to prevent the feed line from interfering with the dipole radiation pattern. The short run of RG174 is decoupled from the base elements with a ferrite choke. This is the dipole base where the telescopic antennas connect to. While the magnetic whip still works perfectly fine, the dipole kit should make it easier to get the antenna outside or in a better position away from noisy computerselectronics, and it also allows for a simple v-dipole configuration for satellite reception.įirst well show and explain about whats included in the set.
