Constantin Posted March 20, 2015 Report Share Posted March 20, 2015 Todd, any diversity system requires 2 antennas. If you unplug one of the 2 antennas it's not surprising that you have "no diversity whatsoever". Am I missing something? Yes, I think he means that channel 2 of each receiver is not getting a signal anymore. Quote Link to comment Share on other sites More sharing options...
Constantin Posted March 20, 2015 Report Share Posted March 20, 2015 If it does antenna diversity, yes.. But I'm not having those results on my Rx-12 at the moment. For antenna diversity you'd need two antennas, too, otherwise it's just simply not diversity anymore. Quote Link to comment Share on other sites More sharing options...
glenn Posted March 20, 2015 Report Share Posted March 20, 2015 In dual mode there should always be signal with either antenna. Give us a call at the shop we can help. Glenn Quote Link to comment Share on other sites More sharing options...
Erkal Taskin Posted March 20, 2015 Report Share Posted March 20, 2015 OK I do not want to hijack this thread but since there are many experts here maybe one can explain a few things related to the topic for an amateur regarding how to pick portable whip antennas for my RX housing that use a 600-715mhz range system. It has been bugging me for a long time and I find it confusing since I do not clearly understand the relation between the length of the antenna and the spectrum its meant to cover. I know you can get harness mounted ones but I rarely use a harness and very rarely end up on a cart which then I could use my RF Venue Diverisity Fin. So %90 of the time I have to rely on the antennas on my RX housing. Also, does it matter if its a thick rubber one or a normal wire like we have on the TX's? Does it matter if they are both vertical or if one is angled? Finally, I often feel that an over crowded set can cause dropouts, Is this really possible?

Derek H Posted March 20, 2015 Report Share Posted March 20, 2015 Todd, when you say when you unplug the antenna all the B channels go to hell what do you mean? From what I remember with my QRX100 that there is always an indication of each antennas receive strength (looks like a cell phone graph) and that when you unplug one antenna it's normal for that graph to go down to zero. It's a nice feature because it will let you know if your antennas are working. In this scenario the B receiver should just switch to the remaining antenna and there's generally no drop out or just a brief one. Are you saying that you completely lose reception of the B channel?

Thanks John, you are right I never thought of that. Back to the topic then. So when you have diversity switch from A to B, is that just switching its polarity for a better signal in regards to finding wether the vertical or the horizontal signals are stronger, or is it doing something else?

Todd Weaver Posted March 21, 2015 Report Share Posted March 21, 2015 Todd, any diversity system requires 2 antennas. If you unplug one of the 2 antennas it's not surprising that you have "no diversity whatsoever". Am I missing something? Yes. Obviously they require two antennas, however my B channel drops out when the B antenna is removed. As a test that my antennas were switching properly in dual mode I removed one antenna.. The B channel drops out without switching to the remaining antenna. Thus,the diversity function is not working. Quote Link to comment Share on other sites More sharing options...

Todd Weaver Posted March 21, 2015 Report Share Posted March 21, 2015 I figured it out. I had a loose connection inside the unit on A channel. Quote Link to comment Share on other sites More sharing options...
