If you need range, go for a mic with a separate RF pack, not one built

Only it it's not body worn. The body packs are allowed a higher ERP than
hand held ones - because the body soaks up RF. Some more than others.

True, you do need to pin it on your hat.

Yup. Or if you want the maximum range fit it to a pole of some sort to get
the advantage of ground plane.

In VHF days I remember using a mag mount transmission aerial on a car with
an ordinary body pack - and a four element Yagi as one receive aerial.
All last minute stuff. Using Microns. And got an estimated 1 mile range.
Just as well because we were running out of time. ;-)

I dunno what they do these days, but you could cover a (horse) racecourt
grandstand (using VHF) for presenters with a 4 element Yagi and and omni
mounted high for line of sight. At 10Mw output from the hand mics.
