One important point! Broad bandwidth is not an always indication of poor efficiency, even though it sometimes is. It is very possible and actually quite common to have low efficiency antennas with na

OK, I'll play the bad guy here - IT CAN"T BE DONE, period! And I am going to challenge those who claim it can be done, to "fish or cut bait." More on that in a minute.. The man asked what changes he

In the spirit of listing things you can't do to artificially make the "L" broad... How about nixing a pathetic ground system at the feed point that wastes half or more of the energy keeping the earth

I have an EZNEC/XZIZL model of an 80 meter dipole that will cover the entire 80 meter band (3.5 to 4.0 MHz) with a VSWR under 2.0:1 with very good efficiency. You do need a fixed LC network (challeng

I wouldn't be surprised if a common vertical section with several horizontal wires of different lengths (spread around the azimuth, not parallel to each other) would do it. Tedious cut and try, but
