The Diamond SB144R2 antenna bracket allows you to easily and conveniently connect two Diamond A144S5R or A144S10R antennas. Connecting two antennas increases the total gain of this system by approximately 3 dB compared to a single antenna.
Made of high-quality aluminum, this stacking bracket is only suitable for parallel-connected VHF Yagi A144 series antennas. The bracket is long enough to ensure the correct distance between two directional antennas in the 2 m band.
The mounting rod has marked locations for antenna installation and fixings for mast mounting. The spacing between the antennas is calculated to provide an optimal combination of parameters (gain and directional properties).
A type SS770R coupling transformer (phase transformer) is required.
