I use #14 solid copper wire, made into an inverted V dipole,
each leg cut to 1 & 1/4 wavelengths. On the odd multiples
of the wave, vswr's should be a flat match if cut accurately
for the frequencies of operation, so at 27.185 ~ the length
of each leg will be 516 and 1/2 inches. The formula for accurate
cuts is 234 / frequency (27.185)= 103.29 inches X 5 (1/4 wave lengths)
= 516 & 1/2 inches.

A dead flat match will be 48 to 52 ohms, an vswr of 1.3 to 1 gives the
antenna impedance of 70 ohms. You can feed this antenna with a 50 ohm
coax, but within 8 feet of the antenna you must coil 10 turns of coax
with a radius of 6 inches, and the same on the other end within 8
feet of the radio. This cancels any standing waves on the coax, as the
coax itself acts as a 3rd leg of the antenna and has the tendency to radiate
signal before it reaches the antenna !

For many years, I used a quarter wave ground plane from
Radio Shack. I was thrilled with it for many years.
Eventually, the center section broke off, and the rest had
to be taken down. I'd love to buy another one. Mine had
solid center and radials. The hollow ones break off, nearly
instantly.
