I am preparing to build another batch of spiral log periodic antenna's
again, with plans for one batch of 200 MHz to 1 GHz, and a batch of the
shorter 300 MHz to 3 GHz, and a really small 1 GHz to 12 GHz.
Construction will be a thick wall fiberglass body, and the element will
be imbedded in the epoxy so that then will not slide around. The antenna
cavity will be filled with foam, and capped with delrin to keep the unit
from getting damaged by rough handling. The mounting block is solid
delrin as opposed to wood, and all antenna's are terminated in an
N-Styled connector. Outside finish is white gell coat just like the other
ones I made, and I will ship these in a new rolling white Hardigg transit
case(s).
I am only planning to make 10-12 sets of three antenna, and each set will
cost $3929 without the Hardigg case, or $4780 for the whole kit including
the three antenna, and the transit cases. For a few hundred extra dollars
I can also provide precision cables, non-metalilc heavy duty tripods, and
a threaded delrin center column.
I may also offer some of my magic pre-tuned 15.734 kHz rods again if
there is enough interest. These bad boys allow you to find hardwired
video camera, and pinholes with astounding ease.
Please contact me privately if you would like a set.
