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

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
