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:
Two outputsto one input.Internal Wide Band or external Phase Shifter .Own (QRO.cz) ferrite cores for high power with great HF parameters.Two relays in series 2x16A in RF lines- 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.
- Size 190 x 120 x 150 mm
- Weight 1.4 kg
Compare antennas:
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 ![]() |
Parameters:
**) Usually optimized for some bands. For example for 6m, 10-15-20m or 160-80-40, but it could be designed for all bands with some compromise.
