Antenna one to two STACK MATCH with BiP/BoP function by OK2ZAW
Stack Match is designed for the stack of antennas - do matching and power splitting totwo antennas.
Could be controlled independently for RX and TX - depends on controller.
Works with Mono-band antennas as well as Tri-band and Multi-band antennas! ( if wide band phase transformer is used )
Main functions:
- Frequency range: 1,8 MHz to 30 MHz (could be made for 6m too).
- Power rating MP < 3kW and HP < 5kW. Normal CW, SSB, RTTY operation. In contest mode: CW, SSB 75% and RTTY 50% of HF power
Two outputsto one input.Internal Wide Band or external Phase Shifter .Antennas are diven IN Phase (BiP) or OUT Phase (BoP) All combinations can be selected: ANT1, ANT2, BiP, BoPOwn (QRO.cz) ferrite cores for high power with great HF parameters.- QRO64-61 for power up to 3kW.
- QRO64-2D-61 for power up to 5kW.
Two relays in series 4x8A in RF lines.- Status LED indicators.
- High quality 2mm PCB.
- PTFE connectors PL-259 , UHF N or 7/16 DIN female with gold plated.
- High quality ATC RF capacitors.
- Relay voltage 12V. Different on request.
- Power consumption < 6W.
- Aluminium shield enclosure.
- Aluminium mounting holder with bracket (pipe max 52mm). More info
- Size 222 x 145 x 75 mm.
- Weight 1.4 kg
Application:
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).Yagi antennas stacking (one tower) Antennas are diven 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
Compare antennas and BiP/BoP:
There is comparison of the four combinations of a stack of two five element Yagi antennas. The possible combinations are as follows:Top - Bottom - Both In Phase and Both Out of Phase |
Both In Phase and Both Out of Phase |
Phasing Line (more in Manual):
Parameters:
**) Designed for 1,8 to 30 MHz, works also on 6m but could be optimalised. You can ask for 6m version.
