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
