Gents:
I neglected to comment in my previous post about a significant issue with
LPs. The boom halves as well as the elements are all above RF ground. Scroll
down a bit on http://www.tennadyne.com/assembly.htm and you'll see a
boom-to-mast insulator. Essentially, the boom halves serve as an open-wire
transmission line from the coax/balun back to the last elements pairs. It is
essential that you keep this in mind when planning your stations. Those who
are in lightning-prone areas may wish to shunt the boom halves to the mast with
suitable RF chokes, perhaps at the boom-to-mast plate, much as some have done
with their Yagi DEs when using them as top-loading for low band operation.
