However, the mismatch SWR for 160 meter band is about 125:1 and that is a wicked mismatch to be sending signals over. Give it a test to see what signal strength you have at 160 (ask others you work) and compare that to 80 meter performance on your antenna. | |
| Nov 25, 2017 at 5:47 | comment | added | K7PEH | It is actually very unusual for a typical 80 meter antenna (used 80-10 with tuner) to also be usable on 160 meter band. The reason is, just like you have found, the mismatch is beyond the matching range of most tuners. You should be concerned though, if you use two tuners to overcome this limitation, about the losses on your feed line. Even with ladder line, your losses could be quite a bit. Continued... | |

formatting; more specific title so it doesn't look like a duplicate of the other "two antenna tuners" question
