I'd like some info regarding "designed for 300 ohms."

On several web forums one of the leading contributors to antenna design and computer modelling is a guy from Delaware, USA with the user name "300ohm" who has done a huge amount of work on the Gray Hoverman, and I also mentioned "j3d", who has also done crucial design work on the Gray Hoverman antennas on his own free time. Nice guys too!

As far as the GH antennas, the impedance at their feed point is 300 ohms, so a person can either connect a preamp with 300 ohm twinlead input at that point or else install a balun there to convert to coax.
