1You can easily set the half wave antenna as an inverted V, horizontal, inclined or vertical radiator. 2Made of premium Printed Circuit Board, very easy to assemble, guarantees stable signal receiving. 3Allows for wide application in wireless signal receiving equipment, electronic equipment and DIY. 4No need for a separate feeder. The high-impedance half-wave line can be matched with a 50 ohm feed point through an integrated impedance matching toroidal transformer rated at 10 watts. 5A high-voltage capacitor is used in the primary of the transformer. The specific heat sink length can be further expanded and the standing wave ratio can be reduced within the range of 80 metres-10metres.
