See the composite screen shot attached. This is only three artists per day at a two-day gig in a city with nine open TV channels.
The spectrum is FULL because the house RF package and the touring acts are all carrying the same frequency bands in UHF TV <608 MHz. No room for anything more at >=300 kHz channel separation. We already have several shared frequencies at different performance times of day.
Take my advice, touring friends. Do whatever you can to acquire as many as possible backup channels of:
PSM1000- L8A (duplex gap), X1 (licensed), X55 (licensed)
Axient Digital- K54 (duplex gap), X55 (licensed)
ULXD (perfect for backline!)- V50, V51, X52, X53, X54
Lectrosonics 941 block (licensed).
*You*are*out*of*your*mind* if you hit the road in USA without some of these backups and think you're going to work 70-artist festivals and/or in metropolis cities without major problems.
Sound companies: buy this stuff. It'll get rented. We know that you have UHF TV band gear that's been on the shelf for the last 18 months making no $, and it has to work for you now. But you must supplement it with gear that works when the old stuff won't. If you're supplying festival house RF, use the freq bands shown above and leave UHF TV open for the touring folks.
