WX0B StackMatch, StackMatch II, and Mini StackMatch

Key Benefits of Both the StackMatch and Mini-StackMatch

bulletEasy hook-up, no complex relay switch networks or carefully cut phase lines
bulletWorks with Tri-band and Multi-band antennas as well as Mono-band antennas
bulletAllows user to steer take-off angles of the stack as well as double beam in two or three directions.
bulletStacking antennas adds considerable GAIN and cleans up the pattern.
bulletBIP-BOP (Both in Phase, Both out of Phase) Can be easily achieved for two Mono-Band or multi-band antennas
bulletTwo Feed line Option allows a second radio to utilize 1 beam in a stack of beams when needed.

The StackMatch System now used by over 5,000 stacks around the world! 

Why trust your stacking system to copy cat products? Go with the best proven reliable solution.  That is why we offer the original Array Solutions lifetime warranty. Built tough and now with over 5,000 in service, you know they are the best!

These guys can take it even in New England, Canadian, Northern EU, and in the brutal arctic circle winters. They also beat the heat and moisture down in the tropics. Get a StackMatch, the gold standard!  Trusted by contesters around the world!

Below you will find several versions of the StackMatch product.

  1. The StackMatch - 3kW standard blue box tower mounted 3 antenna Stackmatch

  3. StackMatch II PLUS - The 5kW StackMatch II with BIP/BOP broadband phasing switch built into it.

  4. HighPower StackMatches - from 5 KW to 20 KW of RF Power

  5. Mini-StackMatch - no relays, just matches 2 or 3 antennas 5KW Standard, 10+ KW Custom built

The StackMatch System, used by over 5,000 stacks around the world! 

 

bulletThe regular StackMatch is designed to stack, match and power split to one, two or three antennas. But if you just want two antennas see the StackMatch II description below.

It will provide the user with all combinations of antenna selection. In a typical three high mono-band or tri-band Yagi stack this would be represented by looking at the dial on the control box or of course its much easier to just look at the LEDs and see what antennas are being selected.  

Added to the switch  is an "AUX." auxiliary position.  It is used to select the dual feed line option or our new 180 degree phase shifter.   With the dual feedline option a second radio can pull a single antenna out of the stack and make a contact.  Then the antenna can be returned to the stack by rotating the switch back to normal stack operation. If the 180 degree phase shifter option is used the Aux position will switch it in and your stack will generate high angle radiation for E-skip propagation to allow you to work close in stations.  Any of these options can be added to an existing StackMatch stack.  

bulletThe StackMatch defaults to the no power position of ALL antennas selected.   This means that in case of a 12V failure, you still have all the antennas selected.

 

bulletThe StackMatch is unique in that it does not rely on 1/4 wave phasing lines to accomplish the match to the antennas, instead the user only has to feed each antenna with EQUAL lengths of coaxial cable. The antennas can be mono-band Yagis, tri-band Yagis, single or tri-band quads, or vertical arrays (see StackMatch for Verticals). For diversity transmission and reception a combination of antennas can be accomplished, such as a Yagi and a vertical.

The StackMatch operates from 1.8 through 30Mhz and is rated at 3 kW CW. Below are typical VSWR and Return Loss plots of a StackMatch & StackMath II from 3.5-31.5 Mhz. 

StackMatches are built using strip line PCBs and sealed relays to deliver this kind of performance.  VSWR is the red line read from the left and return loss is the green line. The measurements are made using 50 ohm dummy loads, you will see a 1.0:1 VSWR in the band with real antennas since they are reactive.  These plots are typical of all StackMatch products.

The 6 meter StackMatch operates from 1.8Mhz through 60Mhz and is rated at 2 kW CW on 6 meters  - We hand tune it to take out all inductance for 60 Mhz operation. It is as flat as the curves above.

 

WX0B StackMatch II and II PLUS

this StackMatch version is now available for two Antennas. Using the same proven reliable circuit board, relays, and lightning prevention circuitry of the original StackMatch, and the same controller but with all of the functions grouped together as in the picture above.  It comes in two versions.

StackMatch II - Two Antennas switch for upper/lower/Both in phase selections

StackMatch II PLUS - 5kW model only - Same features as the StackMatch II but also has a built in 180 degree phase shifter in the remote relay box to give you upper/lower/BIP-BOP (Both in Phase/ Both out of phase) selections.

 The LEDs and the switch displays the antennas selected, Upper, Lower, Both, as well as the Aux "OUT OF PHASE" option. An Array Solutions exclusive function that not only works for mono band antennas but will also work for Tribanders, multibanders, Logs,quads, and verticals.

Specifications for Both StackMatch and StackMatch II

StackMatch II PLUS

The new StackMatch II Plus offers Upper, Lower, BIP and BOP (AUX on the controller). 160 through 6m.

BIP is both antennas in phase, and BOP is both antennas, but 180 degrees out of phase.

The StackMatch II Plus is rated at 3kW DC, 5 kW PEP. No phasing lines required. The 180 degree phase shift is built into the box using our wideband phase shifter technology we've been using for years in our external phase shifter product. It's now all in one convenient package making it nearly plug and play. Requires a 5 conductor control cable. Can also be used for two phased verticals providing in phase and 180 degrees out of phase for broadside and endfire patterns.  Order one here

PB3 for 3 antenna StackMatch PB2 for StackMatch II and StackMatch II Plus

Download Firmware Updater for PB Controllers HERE  New Firmware HERE

Use the new firmware above for programming

Pushbutton StackMatch Controllers

"2 Personalities"

This is primarily for the PB3 three antenna controller

This is the new dual mode StackMatch firmware. Hold in the AUX
button for 3 seconds and release to toggle the mode. Push On/Push Off
mode is indicated by flashing the TOP and AUX LEDs 3 times and the new
multi-select mode is indicated by flashing the MID and AUX LEDs 3 times.
The mode is also shown at power up. Also, the TX configuration is now
saved in the EEPROM and will be loaded when the unit powers up. In multi-select mode (recommended) you select two antennas by pressing both of their buttons at the same time - top two, bottom two or even top & bottom! Press the ALL button and you're back to all 3!

 

Different Transmit Configurations!

What is this for? You might want to always transmit on all 3 antennas (for example) and vary how you receive. Connect PTT to the controller, and it's automatic!

To set the TX stack configuration set the desired antennas as usual during Receive, then hold in the ALL button for longer than 2 seconds and release. The LEDs for the TX antennas will blink 3 times. You can now set the antenna for RX and when the PTT input is grounded it will switch to the TX configuration.

To cancel separate TX/RX configurations, hold in the AUX button for over
2 seconds and release. The AUX LED will blink 3 times indicating TX mode cancelled.

 

Mini StackMatch

This device is basically the StackMatch without the ability to do any switching of antennas. It is a fixed transformer device in a die-cast aluminum weather resistance case. It will provide phasing to two or three 50 ohm antennas without the ability to switch the stack like the standard StackMatch product. They can be combined to allow stacks of 2,5,6,and 9 antennas. 

It comes in 2 or 3 antenna ports with SO239 connectors as standard. N or 7/16DIN connectors can be added as an option.

It has the same specifications as the standard StackMatch and can be used on 6 meters.
