I have never had problems using simple free space path loss for these frequencies. I doubt there is significant cable or waveguide loss. Dragonwaves mount to the antenna and the gain of the antenna is at the interface.
96.6 + 20logD + 20log F Where F & D are GHz and Miles. 96.6 + 10.5 + 25.1 = 132.2 dB From: Jaime Solorza Sent: Wednesday, March 04, 2015 9:31 AM To: Animal Farm Subject: [AFMUG] Smart guys on lost question Hello Smart Dudes on the list: Running a 3.348 mile path for 18 Ghz Dragonwave link to compare what someone else came up with. I am wondering if they used just unfaded free space loss calculation and coming up with a figure 10dB better than mine, I am using unfaded urban area free space loss for mime. I use just free space loss we are within 3db of each other. I added 1 db of cable loss since I do not know if waveguide was used or many other details. I will get all that information on site. I have always engineered paths on conservative side since the start. What are your thoughts Hobson? Thx Jaime Solorza Wireless Systems Architect 915-861-1390
