I received this request from a VE ham.

"What gauge of insulated wire do I need to build a long wire for 20, 40,
80 meters.
In your personal experience, how long must the wires be to operate on
said freqs. I am using an old ts-820 only. I need to build it quick to
listen in on the upcoming Field day this June 23-24, 2007."

Thought I would ask here for opinions

Thanks

Hi Lamont,
the definition of a true long wire is a minimum of 1 wavelength at the
lowest operating frequency. that would be about 256 feet for 80 Meters.
Though a shorter length will work many hams use a random wire that is cut
for a 1/2 wave on 80m about 136 feet or so and use it for 80 thru 10
Meters. however that antenna is not a true longwire until you get up to
40 Meters and above. Long wire are usually end fed with Open wire
feeders and a balanced matching system. they can be very good antennas if
mounted horizontal as high as possible above ground.
Hope this is of help

P.S. A search of the internet will give you much info on Longwire
antennas some good some not so good.

Thanks very much I shall pass it along
Any advice as to wire guage? I have used lamp cord in the past.

for simple, quick and dirty End Feed Wire antenna's, head down to
your local Electrical Supply House and get a 500" Spool of #14
or #16 Stranded Wire for $5.00US, and have yourself a good time
stringing it up in the trees.

In a pinch, that'll work. However... the longer the wire, the more mass &
weight. The softer and/or smaller the wire and the longer the
length/weight, the more stretch. For the best long-term installation,
either hard-drawn copper or copper-covered steel is a much better choice. I
learned that lesson with my first 40m half-wavelength dipole. I used #14
soft-drawn copper... it gradually tuned itself lower in frequency, and then
broke! Many people like to buy wire antenna stuff from The Wireman
(http://www.wireman.com/). I found the product line and pricing to be
better at Davis RF (http://www.davisrf.com/).

Thanks very much to all that replied. I have passed it along to our Canadian
