All antennas can build up “high voltages” during transmit. The ends of a half-wave dipole will have more than 500 Volt potential with 100 Watt input. Don’t touch them when transmitting.

Most new hams quickly learn that the high-frequency bands are where the action is, and getting on the air somewhere between 40- and 160-meters is the way to make those coveted globe-hopping contact… ...

The procedure outlined below can help you understand the process of making and testing an HF RFID antenna. A loop antenna is a tuned LC circuit for a particular frequency, which is 13.56 MHz for the ...
