MH4-400 4 Way Phasing Harness 420 to 470MHz
Antenna arrays can be built-up by stacking and/or baying.
This will achieve additional gain and directivity by phasing two Dipoles vertically, with the MH2 harness, this will obtain a gain of 3dB or 6dB using four Dipoles with the MH4.
The recommended spacing for particular antennas vertically stacked are listed in the specification details. It is recommended that the distance be doubled for talk through applications. The correct phase will only be obtained when the live element on the Dipoles are all upward or downward when vertically stacked with a matching harness.
Matching Harnesses type MH/2 or MH/4 can also be manufactured to include a 5 or 10 degree electrical down-tilt for applications that require a down-tilt from the standard E-Plane configuration.
