Antenne Quagi 432 MHz pour station portable
The wooden lath is the boom. It is necessary to drill holes 3 mm in diameter for the passage of the elements, except for the two frames that will be maintained by the plexiglass parts

Antenne per hf ad uso portatile
Questa e' una personale soluzione, al fine di utilizzare le HF in portatile piu' precisamente dall'auto sfruttando la carrozzeria come piano di terra e naturalmente

Effective HF Mobile Antennas
One of the problems with HF mobile operation, especially on 160, 80 or 40 Meters is antenna efficiency

HF mobile antenna
This mobile antenna is designed for all HF bands from 10 to 80 meters an proved to be very efficient in my travels in South America


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

Atu balanced feeder antenna system

Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
