Antenna for UHF VHF Links →
Skew planar wheel antenna
The popular usage of the Skew-Planar antenna appears to be RC Radio Control enthusiasts as an ideal aircraft antenna due to its omnidirectional and circularly polarization. The low omnidirectional pattern and the circularly polarization
The double turnstile antenna
All the elements are driven via a phasing/impedance matching harbness. This makes construction easy as all the elements are the same length
The Optimum 6 Element Yagi-Antenna
The 144 MHz antenna is designed for a center frequency of 144.4 MHz. The boom is constructed from aluminium tubing with an outer diameter of 25 mm. All elements are constructed from aluminium tubing with an outer diameter of 10 mm
UHF Log-Periodic Array
An experimental LPA for the Australian UHF broadcast TV bands IV and V. They span about 520 MHz to 820 MHz
Una 12 elementi per i 144 MHz
Prima di passare alla descrizione della realizzazione, e' bene descrivere il supportino stesso, in modo che tutti possano rendersi conto della sua validita' tecnica oltre che della praticita'

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
