Re: [IRCA] longwires--elevated or not?
Hi Derek,
My longwires are elevated in the traditional fashion; generally 10-15 feet
off the ground, using the standard 3:1 turns ratio matching transformer,
with isolated coax from the longwire. www.dxing.info has several very good
articles on matching transformers and related antenna info.
I use Home Depot 500 foot spools of THHN stranded #14 wire, splicing the
ends as needed to get 1600 feet for the E/W wire. And since dead trees
usually break the wire several times a year, there are probably 10 or more
splices in the current antenna. Any gauge wire will work since there is no
current flow in the antenna, but wire strength is a big factor for permanent
installations. I used #14 as a compromise between the stronger but more
expensive #12, and a narrower gauge that would break easier. I use poles
over exisiting fences where there are no trees for supports, and use trees
the rest of the run.
IRCA list member Neil Kazaross in Illinois is an expert on using terminated
wire antennas lying on the ground (BOGs--Beverage on Ground)--he's developed
fairly close-spaced parallel-wire BOGs with one wire somewhat shorter than
the other. He'd be the one to ask if you were interested in such antennas.
Generally, BOGs are more directional and have weaker output than a
traditional elevated longwire or Beverage antenna.

Is your wire elevated or is it on the ground??? Is your 1600 all one wire
or is it pieces put together???
Thank you.....
