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

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
