We continue our TECHOMAN antenna offerings with this HF band 80m-10m end fed half wave wire antenna matching balun. Designed for highly portable wire antenna, easily set up as an inverted V, horizontal, sloping, or in the case of higher frequencies, a vertical radiator. Your feed line is essentially the counterpoise, so a separate one is not needed. The high impedance, half wave wire is matched to your 50 ohm feed point by an integral impedance matching toroid transformer, and rated is at 20 watts. The SWR is further broadened and lowered across 80m-10m with a high voltage capacitor on the primary of the transformer using band specific radiator lengths.
Designed to be used without a tuner to give an SWR of ≤2.0 for any portion of the band after optimizing the driven element. For 80m the cable length can be optimized for the upper or lower portion of the band.
A BNC female connector is supplied for connection to your radio.
Depending on the gauge wire you opt to use, the radiating element may be stored wrapped around the device for storage and transportation. Protection will likely be required when used outdoors to protect from rain, moisture, wind, etc
Based on QRPguys design. Made in China.
