Good point. It may well be am sma pigtail I used. It matches my antennas - so that's what matters!G550Ted wrote: Did you actually us an RP-SMA setup or just install the mating (female) connector for a SMA antenna?

Thanx for the description Rob.Rob Thomson wrote:Really nothing to it!
Just unsoldered the old cable. Soldered on the pigtail - and then secured the sma to the case.
Securing the SMA was the hard part.
What I did was.
Sourced a washer that the sma bulkhead connector attached too. Then pushed this into the old hole, by heating it with the tip of a soldering iron. This gave a good and secure metal base for the antenna.
On then inside of then case, I then infilled the hole with some sugru to provide additional purchase for the connector.
Finally, I capped the top off with another washer that was painted black.
Done!

I wonder what the transmitter output power is, and if it can be changed or is changed to the different regions. Using the patch antenna in the UK would probably take you above the legal limit of 100mW ERP....Rob Thomson wrote:It gives the option of using a 5dbi omni, or a 7dbi patch.
On the original D8 receivers the 'whisker' was/is set to 33mm which is about 3mm too long, which would lead to a shorter range. Has this been corrected with the new RX's or the PCB aerials?Rob Thomson wrote:To be fair - the stock antenna goes a long way if you set your receiver up right
Taking the Rigexpert as being fairly accurate as I have no other means of checking its power calibration. The Frsky DJT module power output was measured at 25 mW which is lower than what I would have expected. So the use of the 5dB or the 7dB patch antenna would be a good idea in the UK.Flaps 30 wrote:I wonder what the transmitter output power is, and if it can be changed or is changed to the different regions.

This might be interesting for you - I got myself an It-24 and spend today some time checking the measurement results against a professional spectrum analyzer. See attachment. Everything looks good (considering it's low price tag). As long as the SWR is low it's quite precise. Peak power measurements also seem to make sense. It's build on top of the CC2500 + CC2591 btw, just like the Frsky stuff.Flaps 30 wrote: I am waiting on the delivery (hopefully on Friday) of a nice little unit which will make answering the above questions a simple process, along with helping me construct/modify aerials with some confidence. ----> http://www.rigexpert.com/index?s=it24
