I have since obtained a second 30 foot pushup fiberglass mast from Jackite.com that I now use at the front of the trailer. I have now gone to 72 feet of #16 wire so that I can work 80 meters. The antenna now forms an inverted U shape. Every thing else remains the same.
The real test of this will come in January during Winter Field Day. I'll post follow-up OTA results after that.
