The Hairpin Monopole Antenna
- Numerous questions have been raised concerning its performance, namely How can a balanced structure radiate? and What is its impedance? This article will attempt to answer these questions.
Feeding an End-Fed Antennapop
- End-Fed antennas are NOT balanced systems; but neither are verticals, ground planes, discones, windoms, zepps, Marconis, half-slopers, et al. Additionally, the low-impedance antenna port of your transmitter/receiver is not balanced.
