All Purpose Antenna?

Dilby

Hi all - I was wondeirng if anyone knows of an external antenna that I could attach to my motorhome for 3G/4G/Wi-Fi & Freeview? I have seen some that do wifi and freeview, and some that do 4g/3g and freeview, so it stands to reason that there's an all purpose
one out there that can save me the money, hastle and extra damage to my vehicle by being able to do it all in the one piece of equipment. Any ideas? 



Thanks!
