Here is a simple design for a 6 meter centre fed
dipole antenna, I am using this dipole myself and find it very
it uses a 4 to
1 balun made up of 5 turns of the coaxial feeder RG58 round a 2.5
inch diameter former, and a 4ft length of ladder feed, the ladder
feeder is just a continuation of the top section of the dipole
brought vertically down from the center insulator and spaced 4
inches apart.
The spacers can be any waterproof durable
product, plastic is ideal, below is a diagram of the
antenna. |

The top section of the dipole is
made up of two sections, for these I used 18swg copper wire, which
works very well, tuning the antenna was done by starting with 15ft
for each leg and trimming back until an swr of less than 1.5 to
1 is achieved on the frequency you want to use, although I
found tuning the antenna for the center of the band gave a less
than 1.5 to 1 swr reading right across the 6 Mtr
Band
