[Fourlanders] Identify a combiner

[w4zst at windstream.net]

I have found a couple of Antenna Specialists ACG-2600, TX combiners in the mess out in the building.  Anyone know what they are for and whether they are useful for anything other than the rack mount and massive heat sink on them?  N connector out to antenna, 2 N connectors in from TX1, TX2.

Thanks, Bob

I'm digging out stuff to take to Shelby!!
