Array Solutions Mini StackMaster -- A 4 antenna stack controller for mono-band Yagi stacks.  The Mini StackMaster maintains a 50 ohm match to all 4 antennas in your stack.

You simply attach your 4 equal length 50 ohm feedlines from the antennas to the 4 antenna connectors on the Mini StackMaster. See Figure 1.  Then you attach your 50 ohm feedline to the input connector on the other side. See Figure 2.  The two transmission line transformers are connected to their respective RF connectors, then you seal the connectors with your favorite weather proofing. 

No 70 ohm phase lines to measure and build!

The Mini StackMaster can conservatively can handle more than 5KW CW as well as maintaining great SWR over the band.  This keeps reliability very high, as in all Array Solutions' products. It can be built to handle up to 20 kW.

Matching of the antennas is accomplished through the use of four 1/4-wave professionally built and measured coaxial stubs which attach to the Mini StackMaster.  The user can order the StackMaster with or without Stubs, allowing the user to build their own matching lines and save costs.  

	The Mini-StackMaster operates over the entire HF bands and 6 meters.
	NEMA 4 die cast Aluminum box with gasket.

	SO239 Connectors are standard, Type-N and 7/16 DIN also available.
	Insertion loss – negligible (less than .04 dB) the limit of our spectrum analyzer.
