40m-80m ground planes and a squid pole
The antenna is quite simply, a single vertical radiator with 4 radials laying in the ground. The vertical radiator is held up by the squid pole

Antenne double-bazooka
The double-bazooka consists of 1/2 lambda of coaxial cable cut in the center or twice 1/4 of lambda
Antena doble Bazooka para 80 metros
The antenna called double bazooka was designed to be used in radar by the staff of M.I.T.
1/4 Vertical bazooka antenna for the 40m
I needed a omnidirectional antenna for the 40m here is the schema of the antenna
Coaxial Antennas
I constructed a simple horizontal dipole with each half comprising RG58 coaxial cable about 35 inches 900mm long

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
