[QUOTE="Henry Cohen, post: 68418, member: 123"] Re: Multiple Antennae on IEM transmitter You seem to be presuming the ERP (without the intended splitting) is just enough to cover the performance area. If ERP and field strength at the furthest required coverage point has sufficient link budget (headroom), the 3dB loss from the split will not be harmful. That said however, I typically use directional couplers, generally 10dB (meaning the coupled port is 10dB down from the input with the mainline loss at about .5dB). [/QUOTE]
