Coaxial dipole antenna 128 MHz
The antenna is known as a double bazooka design and is very popular with radio amateurs who make it for 144-146mhz FM operations

Double bazooka coaxial dipole broad-band, W5BGP
The inside sections, do not radiate, but act as quarter-wave shorted stubs which presents high resistive impedance to the feed point at resonance and tends to cancel reactance as frequence off resonant frequencies
Double Bazooka Dipole
consist of a half wavelength piece of coax RG58 with the shield split at the center and the feedline attached to the open ends
Antenne double-bazooka
The double-bazooka consists of 1/2 lambda of coaxial cable cut at its center or twice 1/4 lambda

Noise suppression with X-phase II This device similar devices are known as QRM eliminators or noise killers, makes it possible
The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
Spiderbeam 10-15-20m E' una Yagi tribanda full-size leggera, fatta di tubi in vetroresina e filo
