Re: how good is a rain gutter antenna
In this case, Dave, it's highly likely the gutter system will have much more loss than the transformer. A gutter can be a reasonable antenna if all of the joints have good RF connections-but that

Re: how good is a rain gutter antenna
With the maximum SWR ¡À 2.5 : 1, you must have a lot of loss in the system.

Re: Apologies if flogging a dead horse! CAL Correction?
Oh, and the 'correction' option in the menu is in -newer- nanovna firmware, so if your friends doesn't have it, he doesn't have the latest firmware.
