| My FIL gave me a NIB balun he has had for eons. The paperwork for it says it is broadband from 3 - 40 MHz. Obviously this is from the days prior privileges on 160M. Is there any reason I couldn't use this on 160M? |

It probably just doesn't have enough "balun" to work on 160m, it's a common design compromise. 160m would require twice as many ferrites, so the balun would be twice as long and quite a bit more expensive. 160 isn't a big deal to most amateurs because of the antenna size, noise and propagation, and for those who are active verticals are a lot more common due to the propagation characteristics. If it's the typical ferrite bead style balun, you could always add a few additional ferrites, or a small coil of coax as a feedline choke.
Or just ignore it, and/or ground the feedline shield at some point before it goes in the shack. |
