uberdome Posted September 27, 2016 Report Share Posted September 27, 2016 I have an application that would benefit from the Symmetrical Horn Carrier Class SH-CC-5-90... but only if it is inverted. Is the back of the horn fully sealed? Can it be installed upside-down without damage? Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted September 27, 2016 Report Share Posted September 27, 2016 underdome, welcome on rfelab.com and thanks for interest. Symmetrical Horn Carrier Class has a drain hole on the bottom part of the red cap so it cannot be installed upside down. However if you need to install it on the other side of a tower, you can simply use L mount like on following image: Quote Link to comment Share on other sites More sharing options...
uberdome Posted September 27, 2016 Author Report Share Posted September 27, 2016 Actually, the problem for me is not a left / right issue, in this particular location (on a steeple) I do not have room for the connectors to come out the bottom of the antenna. The spacing would only work if the N-connectors came out the top or side. I'll look into alternative mounting locations. Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted September 29, 2016 Report Share Posted September 29, 2016 uberdome, let us know how it goes. Quote Link to comment Share on other sites More sharing options...
jober Posted January 9, 2017 Report Share Posted January 9, 2017 Shouldn't those horns locations be switched? They seem to be pointing into each others stream. And I think we all learned by watching Ghostbusters, "Don't cross the streams". Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted January 10, 2017 Report Share Posted January 10, 2017 It does not matter if the streams are crossed when you are using them on different frequencies. Quote Link to comment Share on other sites More sharing options...

I wouldn't agree. At such short range signals from one will penetrate heavy in the radio circuits of the other. This is noise and at a very high level. Unless the radio has really good filters or out of working channel frequency rejection I think it is not good. I would never fit them like that...

Guest Mike Posted January 13, 2017 Report Share Posted January 13, 2017 That is right just in case that the antenna is transmitting directly on the other AP. Since horn antennas do not have any side lobes, the other AP has to be in the main lobe. As you can see, this is not happening here, APs are not in the main lobe of the antennas, the APs are shifted and only streams are crossed. The proof that such an installation works is very positive feedback from customer who install it: Quote Link to comment Share on other sites More sharing options...
