MHW-4217 HF Whip Antenna for Mobile

MHW-4217 is an ultra-compact and ultra lightweight, portable HF telescopic WhipAntenna, designed for max. 15…20W QRP operation in 40/20/17m bands. It was published in several amateur radio magazines. It is so easy to operate it: just select desired HF band and tune it for max. reception (Rx noise). Use min. Tx power to tune-it and guide yourself with the tune points marked. Preferably have a QRP TRx equipped with SWR measurement, look for minimum SWR indication on screen. We made 4300km contacts (see video below) with this antenna. Do not expect magic 🙂 but expect it to actually work. It is excellent on reception of HF bands, decent on QSOs on 40/20/17m. Most efficient is on 20m & 17m. *Counterpoise (aprox. 2.5m, with 2mm mini-bannana plug) and BNC  (male-to-male) adapter are included. *Counterpoise most of the time NOT needed, you will notice by experimenting that SWR varies based on position of the antenna kept at shoulder level.
