Stack Match 1-2 manual

This stack match 1-2 device is designed for impedance match two antennas to one TRX. Both outputs are in phase (BiP) or out of phase (BoP). You can match two antennas at the same tower or phase two antennas or use it as a Multi Beaming - antennas to different directions.

Applications

- Yagi antennas stacking (one tower)
- Antennas are driven IN Phase (BiP) or OUT Phase (BoP)
- Multi beaming - antennas to more directions (yagi, vertical, dipole...)
- Phasing two antennas: 0 deg or PH line added. You can stack two mono or multi band antennas.
- Phasing angle can be external with the coax cable or Wide Band with internal transformer (180 deg)

Comparison

There is comparison of the four combinations of a stack of two five elements Yagi antennas. The possible combinations are as follows:

- TOP antenna is 30m / 99ft - BLACK color
- BOTTOM
 antenna in 15m / 50 ft - RED color
- BIP (Both IN Phase)
antennas in 15/30m - 50/90ft - BLUE color. Second image: BLACK color
- BIP (Both OUT Phase)
antennas in 15/30m - 50/90ft - GREEN color. Second image: RED color
