Dutch_12078 Posted March 15, 2022 Report Share Posted March 15, 2022 (edited) Two yagi antennas should be configured at 90 degrees to each other for cross polarization. Splitting one antenna to two inputs does not create an effective MIMO pair. https://support.itel.com/hc/en-us/articles/115004728406-Location-and-Aiming-of-External-LTE-Antennas Edited March 15, 2022 by Dutch_12078 Quote Dutch 2001 GBM Landau 34' Class A F-53 Chassis, Triton V10, TST TPMS 2011 Toyota RAV4 4WD/Remco pump ReadyBrute Elite tow bar/brake system Link to comment Share on other sites More sharing options...
LarryN Posted March 16, 2022 Report Share Posted March 16, 2022 Dutch, I am going to try my single yagi with a Y adapter (somehow I ended up with one of those).....If I buy another Wilson yagi, that matches my current one I am using two coax feeds.

You're defeating the purpose of the MIMO inputs by connecting both to a single antenna, Radio signals vary in strength over their wavelength from nothing to maximum - remember how you had to adjust an old TV rabbit ear antenna for the best reception? Moving the elements just a few inches often made the difference between a good picture or nothing. MIMO antennas work in much the same way - when one antenna is in a null, chances are the other is getting a good signal. Cellular signals have a shorter wavelength than the old analog TV signals so even an inch or two between the two antennas can make a huge difference in the signal strength each receives. You'd be better off connecting the yagi to a single input and putting any antenna, even the stock one, on the other input.

The only "stock" antenna I have is another yagi, or possibly the flat plate window mount, but I think that comes with two leads.......
