For several years now, I have used a variety of antennas for low bands. For 30 and 40 meters, my workhorse has been the HyGain AV Terrific antenna!!!
As I said earlier, I struggled with this antenna myself. I only bought it for use on 80 meters. I also use the HyGain AV which works on 40 through 6 meters.
I thought I would share a few of my notes on tuning up a 6BTV antenna, and constructing a radial field. I have been using a GAP Challenger DXreview herefor the past fifteen years, unbeknownst to me, and over that time, water had been slowly seeping into the tuning harness of the antenna. The harness finally gave up the ghost one day, presenting a dead short to my Solid State ALS amp, review hereas I increased power. Replacing the Challenger was one of the options on the table, but I did not want to do a new install of a Challenger— I remember the last install.
Hustlers exclusive trap design offers the lowest loss possible. A special extrusion process allows trap cover processing to an otherwise unattainable close tolerance, assuring accurate and permanent resonance. Accurate tuning is possible by the wide range of flexibility designed in the antenna.
Tune Around! Readjusting antenna resonance is easy. 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.
When I made my first steps on the HF bands with my indoor loop antenna, I only had slim hopes to have an antenna mounted outdoors in the near future. Living in an apartment, I did not want to ask too much from my landlord — who is always very accommodating and in general exceptionally pleasant to deal with. Of course, I had some very reasonable limitations to deal with: I could not mount anything to the walls or on the roof, and I had to use an existing pole from a satellite dish that was removed several years ago.
