title_body: How to mount XM+ receiver antennas? I like to use XM+ receivers on many drones as they seem to work well and are small/light. What is the best angle and position to mount the antennas of an XM+ receiver in order to get the best signal?
  
  I have often seen XM+ antennas mounted at a 90º from one another on the back of a quad. Is this a good configuration or are there other configurations that have better reception?
upvoted_answer: I really like the way the Joshua Bardwell does it.
  
  He puts one on each rear arm facing forward with a zip-tie and heat-shrink over the top. It places the antennas at 90 degrees to each other and so you get good coverage from at least one antenna.
  
  On the picture below, the yellow line is a zip-tie and red curve is the antenna from the XM+
  
  Remember not to put too much of a tight angle on the antenna wire as it can deform the inside of the cable and have a negative effect on the signal receiving ability.
