For a quickie CB antenna, a vertical dipole (1/2) wave can be made
right from the coax itself You take your coax and very carefully,
without nicking the braided shield, strip 102 inches of the outer
insulation jacket off one end. After removing the outer jacket, start
bunching the shield down the coax from the end. Now, where the outer
jacket and the shield meet, separate the braided shield enough to get
the inner conductor out through the hole in the braid. Pull all of the
inner conductor through and stretch it and the braid out. Be careful
not to skin any of the insulation off the inner conductor. Now attach
an antenna insulator to the end of the inner conductor. Measure the
braided shield. Cut it off at about 106" and attach an antenna
insulator to the end. The total length of the inner and outer conductor
should be about 17 feet (1/2 wave). You can haul it up to any height
you want with a string or rope attached to the insulator on the center
conductor. It's a good idea to coat the end of the coax cable where it
separates with some kind of waterproof sealer. This keeps water from
seeping into the coax, which could cause a high SWR.


Just attach a coax connector on the end of the coax going to your
transceiver and you are on the air. The SWR should be 1.5 or better, if
cut to the proper length. It'll get out about as good as a ¼ wave
ground plane CB radio antenna if you get it up high and in the clear.
Do not hoist this antenna up next to a metal pole, because the metal
will interfere with the antenna's operation and cause a high SWR

just get the lenght's right and you can mount this to a NON conducting
pole eg wood , plastic coated carbon(fishing pole)

this is a good idea to pre make this and mount it out of the way up
high like flat agenst your roof.this way if your main antenna brake's
or goes faulty then you have a backup always ready!!

I have also found that upon making this the swr can start off high.
What i did was get a small piece of pipe(non cond) and wrap the braded
wire around this about 4-6 times. this stebled thing's out and brought
the swr down to 1.4. using slight ajustments to the lenth and coil gap
of the braded wire and keeping the coax from touching the floor you can
get the swr down to 1.2. so got a load of spare coax and a swr meter
then why not have a go and see if you can improve it again
