Re: Max coax length for HF?

I'd worry about intermod / inteference from a wideband pre-amp without any way to take it out of line when not needed. More complicated setup - you need a power supply and a way to tell the difference between a dead preamp and no signal due to no band activity.

At HF, the atmospheric noise is so high, you don't really care about loss as much as problems due to front-end overload. IOW, 3rd order intercept instead of noise figure. At UHF and higher, it's the other way around.

I'd take the loss of a long coax run. Just use a higher gain antenna...
