Doubt the antenna itself is bad. Many DP feeds have no electronics in them just the connectors and a open air column so depending on type of feed I doubt it is the feed itself. My guess is it's more of a incorrect installed feed than anything.
On the cabling have you had it tested for 5GHz operations? I ran across many cables and connectors that are not and each connector might cause 2-3dB signal loss easily and possibly even more the twice expected cable loss on the cabling. You say that cables and pigtails been tested just not how. /Eje ------Original Message------ From: Jayson Baker Sender: [email protected] To: WISPA General List ReplyTo: WISPA General List Subject: [WISPA] WB 58DP - 20dB off? WAS: Candy Sent: Oct 7, 2009 13:08 Got back to both ends of our WB 5.8GHz links today. RadioMobile says it's 10km, we should have 5-degrees up/down tilt, and using the WB dishes see -59dBm. We're seeing only -80dBm on both polarities. Cables are new, professionally made and tested. Pigtails are new, tested. Radios are new, tested. WB dishes... on one end, we have up-tilt of about 2 degrees. On the other end, we have down-tilt of about 8 degrees. Moving a couple degress each way (or, setting both at 5, like RM says) gets almost no signal at all. One is WB 58DP, one is the same, but with the high-performance shroud. Any thoughts? Bad antenna on one end? Jayson -------------------------------------------------------------------------------- WISPA Wants You!
