The Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth. The antenna is designed to be fed with 50 or 75 Ohm Coax Cable of most any length with a Balun. Place a 1:1 Balun on the Antenna end of the Feedline. The Balun matches the Balanced Antenna into the Unbalanced Coax Cable. The balun will keep stray antenna currents off of the Feedline and help to keep stray RF out of the Radio Shack. If a Ferrite Balun is used, the balun needs to be rated at least tw...
