Cheap POS longwire
« on: September 06, 2008, 08:43:11 PM »
Having only a 10m antenna up, I decided to do some experimenting for antennas for HF. I didn\'t have any parts to make a typical dipole. What I did have was an old POS 50 ft extention cord with the ends cut off. I stripped the orange jacket off, seperated the 3 conductors, spliced two of them together giving me 100 ft of wire. One end is connected to my tuner which is capable of tuning a random length wire, from there it goes out the window of my second floor shackm and slopes down to the back yard.

At the moment it is only in a temp setup until I have time to work out something better. But I can\'t complain about it\'s performance.

any wire is an antenna.  good for you for trying.. and the only shortcoming of  POS  wire is it tends to stretch with time and heat.
 you can make a dipole by using any insulator in the center.

cut up  old computer firbeglass cases, throw away printer covers etc.
plastic windows in printers.
 buy a sheet of 1/4 inch  plexy  at   ACE or home depot.
or  1/8 inch plexy and  hot glue  two or three  pieces together.

a good trick is to use several \'black\'  zip ties to hold a short piece of
1/8 in  rubber  auto hose to the center insulator and tape  to the  lead  as a strain relief...

other wise the lead will break on one side and  antenna acts funny  and a dipole cant be checked with an ohm meter like a closed loop beam can sometimes.
use pulleys on the ends so you can raise and lower two dozen times  to get it right.

have fun.
