- Is it advantageous to make both the vertical and the horizontal sections "fat" (for improved bandwidth), or is it enough to "fatten" the vertical (radiating) section ? How much BW will 3" diameter sp

- The horizontal section also radiates, more or less than the vertical depends on the specifics. Easy to see in a very simple NEC model. If you are opposed to radiation from the horizontal on principle

- I had plenty of bandwidth with my L. Maybe that means I have plenty of loss too. :( I had no issues working nearly everyone I heard. I wonder what making a "cage" on the vertical section would do. So

- A very important caution about the performance of T-verticals vs. Inverted-L verticals. If the performance of your 40 meter antennas is important to you and your T-vertical is within 300 feet of your

- About 16 years ago I modified an ordinary inverted L (with c60 feet vertical) using 4 vertical #14 wires spaced in a one-foot square--hoping to broaden the TX band width. No sign of improved bandwidt

- My base insulated tower is 127' of Rohn 25G. An 80m half-wave dipole is attached at the 119' level, the ends of which droop down to about 100' at each end, with runs of Phillystran from the ends of t
