[QUOTE="Caley Monahon-Ward, post: 10327, member: 2048"] I am in the midst of tech for a theatre gig going up Friday. I've had some RF problems and think I have a diagnosis, but wanted to run it by the peanut gallery... Or even better, an expert or two. I have a 10ch rental system comprised of a mix of Sennheiser SK500 and SK100 transmitters and Evo 100 and 500 G3 receivers across the A and G bands. The freqs I have are shop-coordinated and all clear when transmitters are powered down. A pair of what I believe are Sennheiser 12AD active LDPA antennas and three ASA1 splitters. My antennas are in a wing about 8' off the ground on sidelight booms. 25' cables of something beefy -- maybe PWS 9046? Performers are generally 5-30 feet from the antennas but I'll need probably 60' of reach for one scene (I'll have line of sight to at least one antenna for that -- the best I could do). I'm getting inconsistent reception range and occasional dropouts or hits. When my A2 walked the room with a single channel powered on we had vastly better reception than when performers are onstage. Seems like a case of intermod caused by too much RF gain, right? Should I demand passive paddles? Tomorrow I'll try subbing in passive omnis to see if that clears up. Not sure I'll get the range I need with omnis, though. I also have the option of lowering the TX power on the SK500s, which are about 2/3s of the TXs I have.
