Post ma5b type beam
i have the urge to get a ma5b to replace my cobweb type antenna ~(very small garden /bungalow)
i know these are a compromise etc the questions i have been asking my self are as following , as this needs a rotator is it wise to put a vhf (6 or 2/70 ) yagi type above it and then my white stick vertical (vhf) due to the way its made ie capacitor top hats etc will they effect its rf pattern ,vswr workings etc
now the real dumb question is a mini beam really any better than a cobweb at 30ish feet ?

An MA5B will be a noticeable improvement over a Cobweb at the same height; but remember that the MA5B is particularly narrowband on 20m, and it's a simple dipole on 17m and 12m. Given a free choice I would go with the MA5B every time.

There should be negligible interaction with a VHF vertical, or with a VHF beam if you get enough separation. Then it becomes a mechanical issue.

I cannot give you a comparison between the two but I can certainly recommend the MA5B I put mine up in November.
I am impressed.
