This one also tuned to a very pleasing SWR below 1. Retractable steps on your motorhome? In got my novice and ground mounted a 4BTV with a handful of radials. I was hoping that this antenna would perform well and was very happy to see that it does work very well. The product reviews aren't that helpful, but the forums are. Mobile antennas can also be used successfully. At my age, getting up the energy to bury 12 more 25 foot wires under the sod is somewhat difficult.

Basic Assembly and Enhanced Operating Assembly: Since the portion of 80m is only about kHz, I decided to set the center frequency to be 3. You might "miss the dip" as it passes your target frequency. Page 15 The antenna performs nearly the same with an equal number of radials squeezed into directions that cover smaller arcs. If you don't add radials performance will suffer. Slightly loosen the band clamp at the bottom of the trap sleeve, NOT the clamp on the larger tube below.

A spring also from Radio Shack was added to the fitting. Louis Vertical, widely known as the SLV, is a great all band vertical antenna for portable use. It may improve the match on the lowest band. When desired tuning cannot be achieved by the adjustments in the Hustler manual, re-tuning the vertical for in-band resonance is best done by adjusting the traps. Simply 18 feet of aluminum up, no visable radials. Because I have an extensive ground radial system in place I guessed this was why the readings were so low.
Perhaps I should think of the coax as a wear item. The vertical is mounted to a 4"x4" post sunk into the ground. Just how close to a house can you ground mount a Hustler 4BTV antenna and still get good performance from it? The product reviews aren't that helpful, but the forums are. I am only going to be using about 50 watts into this antenna and I will use about 60 radials.
