Live video (FPV) from 1:1 race cars / bikes

I was watching some racing on the weekend and was wondering what systems they use to get the live in car and off bike footage.

They only appear to have whip antennas which we all know offer pretty limited performance but the picture always seems rock solid and fairly hi res.

I guess in most cases they aren't transmitting further than a km but what about places like the Nurburgring? Is it possible they use multiple receiver towers on a super sized diversity switch? How do they minimise interference when they have so many cars transmitting?

So what are they using? Frequency and equipment wise...

The broadcast itself is delayed so they don't need truly live video. These days they're
typically using digital video systems (thus no static) that start at about $20k (1tx/rx pair) with too much latency
to use for our purposes. They use helicopters (or blimps) as relays (have been doing that
for decades).

Motogp uses Gigawave HD transmitters. COFDM digital, which is huge for multipath and penetration. The latency is to high for us to use, but hopefully the technology will trickle down here shortly.

here's rossi's GP bike back in 2010:

Yup, the other used in racing is multiple antennas placed strategically around the track. This prevents signal loss from bridges and provides coverage if the helos are grounded by weather.
