Description
Function:
K4EDF end-feed antenna, HAM four-band antenna, SDR short-wave antenna
The K4EDF is a four-band end-fed antenna. The advantage is that it has a very wide working bandwidth compared to other types of antennas (refer to the measured SWR graph). Normally resonant from the ground for more than 1 meter at the frequency we need to work. on. And the height change does not affect the resonance point very much, so basically it can be used without trimming, which is very suitable for an antenna for beginners. The disadvantage is that the matching method is to use a high-ratio conversion balun. Because of the high ratio of the turns ratio and the magnetic flux density and the upper limit of the magnetic flux operating frequency, the antenna is very suitable for beginners (not suitable for long-term continuous launch). , suitable for interval transmission and reception), amateur band SDR reception. There is no problem in receiving broadcasts, and it is also suitable for broadcasters. The custom magnetic ring currently used reduces the loss to the lowest limit, and the actual test is safely transmitted with 100W SSB for 30 minutes! (Normal test balun only takes 10 minutes to continuously emit normal temperature and is qualified), we are all passed the super-strength violence test!
Main parameters: 7MHZ 14MHZ 21MHZ 28MHZ four-band, standing wave less than 1.5, withstand power 100WPEP, balun insertion loss of about 1.5DB, vibrator with 1.5 square MM pure copper multi-strand, the antenna length is about 20 meters.
Erection method: horizontal, diagonal, vertical
