alidav Posted November 27, 2018 Report Share Posted November 27, 2018 I have replaced the antenna on the receiver with a sma connector, and tested it with the new antenna, i switched on a tx and moved quite far, with 2 receivers on, the new modified and one standard, this one had a stronger rf, I did replace the standard antenna and nothing changed, the rf was still weaker. so I supposed that the problem could exist already before having fiddled with antennas, my suspicion was about having done what is your idea?

ao Posted November 27, 2018 Report Share Posted November 27, 2018 make sure you haven’t replaced the antenna with an “rpa” version that isn’t making a connection Quote Link to comment Share on other sites More sharing options...
alidav Posted November 27, 2018 Author Report Share Posted November 27, 2018 I replaced again with the standard antenna Quote Link to comment Share on other sites More sharing options...
Nate C Posted November 27, 2018 Report Share Posted November 27, 2018 Also make sure the wire connected to the pin isn't touching the outer pert of the SMA connector in any way. This will significantly reduce the range. I learnt this the hard way by using a wire with shielding to thick to fit properly into the SMA.

mark kirchner Posted November 28, 2018 Report Share Posted November 28, 2018 You can see that soldering on the circuit board one needs to be very precise. This is a G3 I did a few years ago. Quote Link to comment Share on other sites More sharing options...

I learnt this the hard way by using a wire with shielding to thick to fit properly into the SMA. 3 this is hard to accomplish especially with budget Chinese connectors, ill buy more expensive one with an ipx cable already wired on the distances involved here are around 15 meters with some wall in between, I've already done some other sma replacement and it works good, much stronger than this one. as I've said I have replaced again the stock antenna and nothing changed. I can use this receiver anyway, avoiding to use where have long distances involved, but id like to have all my gear at 100%.(also the spares) 17 hours ago, mark kirchner said: You can see that soldering on the circuit board one needs to be very precise.

alidav Posted April 11, 2019 Author Report Share Posted April 11, 2019 sorry to resume this conversation after many weeks, do you think this can accomplish the goal? to put an sma connector on sennheisers ?https://it.aliexpress.com/item/5pcs-SMA-Connector-Cable-Female-to-uFL-u-FL-IPX-IPEX-RF-Or-NO-Connector-Coax/32909354468.html?spm=a2g0y.10010108.1000016.1.35a339ebSPmqgI&isOrigTitle=true Quote Link to comment Share on other sites More sharing options...
