You have a point Mark. I agree that a simple 1/4 wave groundplane is more
study and very easy to make using an so-239 and some piano wire. Steel wire can be soldered right into the back, four bolts with nuts and four more peaces of wire around 19" long with a bit of a downward bend and you have a very good antenna. It's worth noting that you don't actually need four radials. Two radials (on opposite sides of the feedpoint, bent down at around 45 degrees) will produce a perfectly satisfactory ground-plane. The patterns of 2- and 4-radial ground plane antennas are almost indistinguishable. A 4-radial antenna may *look* as if it would produce a much more circular pattern than a 2-radial antenna, but this doesn't turn out to actually be the case. -- Dave Platt AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
