I knew that I PAID my dues for a reason….!
:) I wasn’t treated this way before. I guess I get what I paid for…Is there a
money-back policy? - Cliff From: [EMAIL PROTECTED]

wasn't related to you ? We proposed a spectrum analysis for a client. This analysis was to be performed with a hand-held spectrum analyzer at the height that the equipment was to be mounted. Our offer was rejected. However, we were asked to provide the climber for the other party's analysis. Their analysis was performed as follows: 1. Using a 'nice' spectrum analyzer a. the analyzer remained in their truck b. the antenna from a 5.8Ghz Redline system was hauled about 140' c. the original RF cable used was RG6 for 140'(duh?) d. the next 140' of RF cable used was LMR400 e. we know that we shoot directly through one of the sites surveyed with 5.8Ghz P2P link, and have 5.8 P2Mp links at two other locations surveyed f. all analysis showed no RF interference (go figure!) I'm not an RF engineer, so would someone help me to explain why there was no 5.8Ghz interference shown at these locations even though I know there to be other 5.8Ghz equipment hitting the towers tested. What is the RF cable loss at 140' of using LMR400 as described above? Also factor in about 4 connectors to adapt the RF cable from the analyzer to the antenna. Is this a valid analysis, or am I wrong to comment to this customer that I feel this analysis if flawed? "Ammunition" that anyone is willing to supply would be appreciated as well as advice for me to keep my mouth shut. :) - Cliff |
