My name is Dave Williams and I have been building antennas since I was about 14 years old. That was quite some time ago. ; :-) Started out with dipoles,long-wires, inverted V then moved on to yagis, moxons, J-Pole, slim-jim, verticals, and portable / emergiency type antennas.<br><br>I find the portable antennas I make to operate just as good as the more antennas! The only difference, and it's a small one is the fact that the portable being made of wire, have a smaller bandwidth. That said - I still get about 1.1:1 at center frequency, and no more than 1.5:1 at the band edges.
