These mini sets are plug and play with a guaranteed VSWR of between 1:5 -1 and 2.0 to one. This is tuning your ariel to the best performance right across the channels , these are base loaded and pre tuned but also not tuneable. I’d still pop the meter on there just to check they are somewhere in the region. An iffy solder joint could bugger it completely so it’s worth checking. This will be more than good enough for what we’re looking for. If we wanted to increase range (DB gain) then we would go for something like Dav has or Easy has and that would multiply your output power and reception too. Tuning the Ariel’s is trying to match the ariel with the frequencies that you’re transieving on and each channel has a different frequency so it’s impossible to make it perfectly tuned to each channel so an average is applied by tuning to the best you can get on your highest and lowest channel / frequency. This is also what the base loading is all about, it’s a winding to match the eleven metres that we’re on or a direct fraction of it, like a quarter wave antenna or a half wave like a home base antenna . Most but not all of the mobile stuff is a quarter wave length. So if you strip one down it’ll be a quarter of eleven metres long ish. With the Westy pop top set up, or any large fibreglass you are never gonna have as good a setup as a tin top but hey Ho.
