Hi Mike,
 Antenna Gain and coax do not mean as much as height. Get a chopper to hang
your antenna from a low cloud. Seriously try to get higher or closer to the
 wavelngth of interest. Shortened antennas don't radiate as well as long
ones. Don't spend much money on improving the loss by getting
 low-losscoax,
 HEIGHT, HEIGHT, HEIGGHT.
