Feature:1. PORTABLE AND EASY TO USE: This is a portable small loop antenna, which is easy and fast to set up the antenna for your shortwave transceiver antenna2. PRACTICAL FUNCTION: Let you enjoy the pleasure of multi band reception and communication at indoors, window, balconies and outdoors3. REDUCE INTERFERENCE: Interference resistant, possess low standing wave, strong directionality, full frequency band4. EXTENDED USE METHOD: Remove the pull rod antenna. Connect a 20 meter long wire. The long cable frame is erected high or on the roof. Tuning method is the same as above. The launch efficiency will increase several times. This method can replace the pull rod antenna5. MAIN APPLICATIONS: Used for signal receiving and sending, aluminum alloy and steel material is durable, corrosion resistantSpecification:Item Type: QRP Shortwave AntennaMaterial: Aluminum alloy, steelPurpose: Signal receptionBasic Parameters: FRQ: 3.5~30MHZ, 50~54MHZ, 76~108MHZ, 117~136MHZ, 136~174MHZ, 400~470MHZ.Package List:1 x Tuner1 x Antenna1 x Connector1 x Antenna Storage TubeNote:Outdoor use is the best, indoor use antenna as close as possible to the window, reinforced concrete fully enclosed environment, against the wall and other environments, part of the frequency band standing wave ratio is not ideal.
