I have a 4X9 XPOL array from gulf alpha antennas, works well, I have worked
many DXCC with this one and the booms are only 15ft long. I use a screw jack
but I imagine a 5500 would work as long as everything is balanced.

These are fine antennas, just hard to get. I have used M2 XP20 and XP28's
but I am very happy with the compact array and smaller booms.

73 all and great input from all.

Antenna is a full size 9 element wide spaced computer optimized yagi. Has machined aluminum connection box as the core of the antenna feed system. To give our antennas a little better bandwidth SWR, we always make the driven element a larger diameter. This model has a 1/4" dia. driven element and T match rods. Other elements are 3/16" dia. , all elements are solid rods. Aluminum members are 6063 and 6061 for best corrosion resistance. All hardware is stainless steel. Uses a 4:1 teflon mil spec. coaxal balun which allows the balanced feed of the antenna to be fed with 50 Ohm unbalanced coaxial cable and uses superior T match system for best radiation pattern and good matching. Antenna is designed for service in EME communications.

Additional features of this great antenna include a double boom to mast plate which uses 4 V clamps and these clamps are spread over a greater distance. 4 clamps around the mast will result in greater holding power against the twisting forces preventing the antenna from turning and becoming out of sync with the rotor.

Innovative element mounting system makes assembly a pleasure and long term reliability assured, see pictures above.
