Wanted to update this. I checked the voltage coming out of the XD-AD8 and it measured around 8.6 volts. The wall adapter measures 9.3 volts. The receivers must be quite sensitive to the incoming voltage? My only guess is that something happened to the xd-ad8 that messed with the voltage. ?? -Brian

I'll have to dig into it when I get the unit back. (It's currently being shipped home with all our other equipment). I also hate the non locking power. I can't tell you how many times they've come unplugged when fiddling with other cables in the rack.

So it looks like we had a failure with the XD-AD8 power distribution. Towards the end of a weeklong event, we lost all of our wireless mic's. After a good bit of troubleshooting, it appears something happened with the power distribution. So in the above image, the top receiver is powered directly by the wall plug. The bottom one is powered by the xd-ad8. Basically the screen was dimly lit, and the transmitter status showed as muted. The transmitter did transmit a signal. Since I of course had all the original power adapters at home and not on site, we had to run around and find universal 9v adapters for our 9 receivers. Anyone know what happened? Is there a fix? The antenna distribution still seemed to be powered and worked. Thanks, -Brian TESN.US

Thanks! That's the kind of info I was looking for. I wasn't sure what would be the best placement in that scenario. My uneducated thought was that an antenna on each end would ensure full coverage, but I'm starting to understand that both antenna need to receive the signal, not just one at a time. -Brian

Mounting a rack in the roof wouldn't be a viable option in a majority of the locations we go to. There isn't always a truss or catwalks. Sometimes we just have i-beams to attach cameras to. It's possible to get the antenna in the roof, but not in all the venues. We could possibly get the receivers at the side of the rink in the middle at ground level. And are you talking an xlr snake running from the receivers up to our location (mixer)? We actually starting thinking down that route after our latest event. We have a digital mixer and they make a digital snake that only requires running a cat6 cable from the mixer to the receiver location. http://www.tesn.us/uploads.html So in the picture linked above, we could most likely get the receivers to the red X. From there we need to cover the area of the ice highlighted in red. Thoughts on best placement again? Ground level. We'll most likely be grabbing some LMR400 cable for the antennas, just to be safe. Appreciate the help! -Brian

That's actually possible. We are usually hanging cameras over the playing surfaces. In fact we're using trusses at our next event. So it's feasible. What's the recommendations on cabling? Is it possible to make 300' runs with those antennas? What type of cable? Thanks, -Brian

Hi all, So my company puts on live curling broadcasts. We mic up 8 players with XD-V75 wireless lav's. We have the XD-AD8 and the P180 antennas. We also have a handheld for sideline reporting, so we actually have 9 wireless going at once. We've pretty much experienced dropouts at every event. We can be in small and large hockey arenas or smaller curling clubs. Generally the antenna/receivers are at one end of the arena pointing out over the ice. I've been running in RF1 mode since most of these venues have some sort of Wi-fi available to the public. We get most of our dropouts when the players are on the far end of the ice. Especially when players are facing us, with the pack on their back. We have other issues such as players clothing covering up the packs. That's sort of out of our control because we don't want to force players to certain clothing (it's cold out there). I generally keep the antenna about 6 feet above the players heads, and play around with placement and direction. I think we have 100' rg58 cables max. I've never successfully eliminated the dropouts. I usually don't have enough time to troubleshoot as I'm running around doing 100 other things. So I'm looking for some advice on ideal placement. The beauty of the sport is that the player locations are really fixed. Think between the two goals in a hockey rink. They pretty much just move back and forth between those, facing one direction or another. I would think if we could get one antenna on each end of the rink that would be ideal. But that might be a 300 foot run or more to our location for the far end. Is there cabling that could be used with the P180's that would allow that? Are there more directional antenna, or higher powered ones for the long distances? Any other ideas? Thanks! -Brian
