2m-70cm antennas super jpole
Frequency 144 MHz, 1,417 meters 4 feet ,7.79 inches - Frequency 440 MHz,0,463 meters, 1 feef, 6,26 inches
Simple 50MHz-J-Pole-Antenna
The bandwidth for a SWR 1,5 is greater than 1 MHz. The gain and pattern are the same as with a normal vertical dipole
Jpole Bibanda per i 2metri e i 70cm
Angolo di radiazione piuttosto alto, e' una antenna omnidirezionale utilizzabile anche per il traffico sui satelliti
Building A 2-meter J-Pole Antenna
So this J-pole is made for 146 Mhz so all of the lengths pertain to that frequency
