Have a few questions about the new Penetrator spt-500. When I say new, I'm talking about the newest version with the new style of matching network. It's no longer the traditional wire with the two humps. It's now shorter and made of a flat piece of cut out aluminum.
Anyways, I've been using a Sirio Tornado 27 for years, SWR was excellent across all 40 channels. The wind finally snapped the plastic piece at the bottom so that was that. Just about everyone and their brother suggested getting the Penetrator Spt-500. However when it came it had the new style matching network. Anyways, put it up and adjust it the best I could with both my MJF-259b and my inline SWR meter. I prefer to adjust for the lowest on channel 20. So 20 is 1.1, however the SWR climbs up the closer you get to both channel 1 and 40 with the middle being the lowest.
My Sirio Tornado 27 was very broadbanded, however this spt-500 doesn't seem to be. With 2000 watts going out, I'm seeing 10 watts coming back on channel 20, however 30 watts coming back on both 1 and 40 due to the higher SWR. I don't want to hurt my amp while on channel 6 or 38.
Has anyone else had this issue? Any possible suggestions? Thank you.
