OC-Chad Posted February 25 Report Share Posted February 25 What is the best way to determine how down tilt affects the 30degree horn pattern? We have a 200ft tower that we are looking at putting a 30degree horn on and want to make sure we are maximizing its potential for a group of homes between 1-2 miles from the base of the tower. Radio will be a UBNT LTU Rocket on the horn. And likely LTU-LR stations. I played around a bit with the link calc 2.0 but it is acting like I'm putting ltu rockets as every cpe which isn't going to be the case. It also never seems to show me an actual color gradient of coverage. I've mapped it in the UISP Design center and have it set as a 30deg 20db custom antenna but understand it won't have the exact pattern of your horn and is more symmetrical in design. I believe that the azimuth of 289 would be correct, but don't understand how the downtilt plays into the design. I'm also trying to understand what the practical distances from this antenna and horn would be. I've attached what the UISP tool believes the signal would look like. How far off from this would I expect an asymmetric horn to be, and would this be the right horn for this use case? One of the concerns is that houses 7 and 8 are on the very edges. If I were to pick one over the other, it would be trying to keep 7. Thanks for any and all help with this. Quote Link to comment Share on other sites More sharing options...
