"Mobile" doesn't mean "in a car"

I'm going to have a rant about people who seem to think the "mobile" suffix means "in a car". I often now specify exactly how I am mobile but you should not assume car mobile without qualification.

"Mobile" means the Radio Equipment is located in the United Kingdom:
    i. in or on any vehicle or conveyance;
    ii. on the person of the Licensee where the Licensee is a pedestrian
    iii. on any Vessel on Inland Waters;"

There are at least six modes of transport fitting this definition which I use the radio from and none of them are a car.

So, don't call your product a mobile antenna when you really mean it's an antenna for motorcars.
