Subject: Re: SWR which should use Wed Dec 09, 2020 4:21 am
I'm guessing you want to be able to use CEPT and UKFM?
27.5 Mhz, it's smack in the middle of both.
And by the way don't expect that measurement to be a guarantee it'll be a low SWR there. That measurement is merely a start point to get you in the ball park. There's lots of things that can affect that, including whether or not you've got a decent RF ground and are using a RF choke at the antenna. If you're not then your coax can become part of that and its length will affect the tuning.
