80 Meter Tower Vertical

First was a single wire that was matched for 80m using an omega match. This worked ok, but I started with just seven 50-foot radials. When I added eight more, the shunt worked much

80 Meter Antenna
I ran a small single wire from the soffit directly down the side of the building

80 meter doublet antenna design
It is basically an 80-meter dipole fed by a length of 450 ohm ladder line into a balanced antenna tuner

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
