All in one antenna; wifi/3g/lte/freeview
Hi all - no idea which area to post this one in as it's pretty all-inclusive, so apologies if it's not in the right spot.
I recently purchased a campervan and want to be able to work away in it from time to time using a combination of 3g/4g(lte) and wifi. I am aware that omni directional wifi antennas these days can give you some pretty good long range coverage these days, and combined with mobile reception I figured I'd have the best of both worlds (currently I have a little 3g/4g mifi device that runs off 12v which takes external aerials). I also have a portable tv which takes an external aerial for Freeview (UK digital tv). My question is should I be pursuing an antenna that does the lot, does one even exist, or would there be too many compromises?
The reason I ask is when shopping for the three antennas I'd need (mobile broadband, wifi and free view) some of them do more than one thing ; so a free view also picks up wifi and a 3g/4g also picks up wifi. This leads me to wonder if therefore one can do all 3?
It'd need to be of a decent size so it could fit on my motorhome roof; but anything that can save me drilling extra holes would be nice!
