distance between A and B = in meters 100/frequency (mhz)
space between wires (C) in meters = 3/frequency (mhz)
minimum height of lowest point = approx 10 meters

PARTS:

antenna wire: calculated length times 2 plus 10 percent
              I used #12 prestolite 2-80 M13486/1-7
              This is neopreme miltary rope used
              in airborne hf systems.

balun:   PB-9 from Palomar Engineers (619) 747 3343
coax:    RG58CU (this has stranded center conductor)
pulley:  large enough to seat 1/4" rope and not jump out
rope:    1/4" nylon rope (yellow stuff), length - 150 feet aux
wood:    1" by 1" by 10 feet long to make end and center
         supports (broken hockey sticks work best).
protect: exterior wood stain or varnish to treat supports

HINTS: 1 meter = 39.37 inches, 3.281 feet
       make wood stress relief for resistor and balun

The above antenna is based upon the article in the 1988
publication of the WORLD RADIO TV HANDBOOK. In the article
they used a length of 15 meters which gave good results from
3.5 mhz to 25 mhz. In my case I reduced this to 14.2 meters
to fit my space limitations. Also the balun is a 50:450 ohm
or a 1:9 ratio, this gives a possible swr of 1.1:1, not bad
in my books.

A quick rule of thumb to obtain the 30 degree angle is to
take your total length and divide it by 2, the figure you
have is the height that you must go up.

In my set up the low end is attached to the roof. The high
end is up a large tree, secured around the trunk and down
via a pulley to ground level. This permits me to hoist it up
and down with out going up the roof or tree. The sketch
below should give you an idea.
