Antena ringo para 144 MHz
The ringo antenna is commercially manufactured and very easy to build.It consists of an irradiating element and its base that is connected to the pipe that holds it, acts as earth or ground of the antenna
Antenna building for 70 cm
The opened DE-Box. The coax used is MIL-quality RG58 , the shown split open coax ends are about max. length that I would tolerate
Antenas fijas para satelites
The Turnstile are two directional two elements, physically crossed at right angles and electrically offset 90' to obtain a circular polarization
Antenna 144/430
This vertical VHF antenna is convenient as a base for a dual-band portable. It allows you to fully realize both the power of the transmitter and the sensitivity of the receiver
Antenna Ground Plane 1/4 d'onda autocostruita per VHF-UHF
Questa antenna puo' funzionare da circa 75 MHz a... infiniti MHz, semplicemente allungando o accorciando i 5 stili secondo la seguente formula...
