Weight [Weight]: 27 kg NOTE: You can add 1 element for which you need to do a separate power supply. It will then worked as a rotary dipole and here we choose the following frequencies: 10, 7, 3.5, 3.8 MHz. With version Dipol 10 and 7 MHz are your short and long, about which versions can be suspended decides mast height at which the base antenna is installed. (*) The GXP-7 antenna band 18 and 24 MHz is separated and can occur logoperiodyku SWR increased, which can compensate for the length of the power cord. NOTE: You can add one element for Which do you need it for a separate power supply. It will then worked as a rotary dipoles and here we choose the Help Us frequencies: 10, 7, 3.5, 3.8 MHz. When chose dipole version 10 and 7 MHz are your short and long, about Which versions can hang determines the height of the mast, he Which is the basic antenna installed. (*) Bands 18 and 24 MHz in the antenna GXP-7 are separated In this logoperiodic with Increased SWR, Which can be compensate for the length of the feeder. – See More Link
