HF20A Short Wave Full-Length Single-Line Traveling Wave …, Perth

Description HF20A is a multi purpose short wave full length single line traveling wave antenna with high radiation efficiency and convenient installation It can be used for personal portable stations and temporary base stations in the field Used to compensate for the presence of NVIS blind spots in general antennas When the cable is erected the 25W 50W portable platform can be used for 0 800km and the 125W vehicle can be used for 0 1500km When the flat pull is erected the directional communication distance is further Specification 1 Maximum power 1000W average power 50W2 Working frequency 0 5 30MHZ SWR2 03 Standard vibrator 20 meters4 Vibrator material 1 1 5mm multi strand copper core wire5 Stainless steel ground nail 2 pieces self provided 6 uses a larger and better magnetic ring so that the parameters are more ideal Can withstand 200W of high power when production it must be tested by 200W high power for a long time Installation prompt 1 The roof is fixed for a long time It is not necessary to use the ground anchor when installing Connect the two tail ends of the antenna directly with one wire to connect the two tail ends or directly connect the two tail ends directly SWR Ideal simple and practical The basic condition for the operation of this antenna is that the two tails must form an indirect or direct loop to work 2 In actual outdoor use if the ground anchor is not in good contact the antenna will not form a loop and the SWR will
