Antenna for UHF VHF Links →
Antenna double bands 144/432 mhz
Questa antenna e' lunga circa 1,5 metri solo circa 30 centimetri in piu' di una quattro elementi a spaziatura costante classica
Antenna YAGI a 6 elementi per i 2 metri
Il boom e' lungo 1,75 m sezione 1,8 x 1,8 cm, il riflettore 50,3 cm, il radiatore 48,9 cm, d1 44,9cm, d2 44,3 cm, d3 40,8 cm, d4 39,5cm
Antenna Yagi 4 elementi UHF
Adaptation with hairpin on uhf is very functional and stable, and above all it is preferable to the match range
Antenna Double loop rx satellite 137.5mhz
operating frequency = 130 to 170 MHz ,center frequency = 137.5 MHz, perimeter of loops = 227 cm, material used = copper or aluminum = 227x3x0.2 cm, horizontal polarization gain 3 dbd
Antenna for 6 meter band Halo
A square folded dipole radiates in all directions, with -4dB gain on the sides compared to the front and back side

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
