By same horizontal level, you mean when the top of the gopro is at the same height as the part of the antenna where the ground wire and active wire splits? If I were to place the antenna (default length) on the wing, will the distance be sufficient if I were to place the receiver at the place where the wing is slotted into the fuselage with the antenna exiting from that slot? Even if the gopro is used for recording, noise will also be produced? Thank you!

I don't know what else you want me to tell you. You're overthinking this.
Just don't put them close to each other.

RL has a low power range test mode. Use it.

have you ever tried those rc heater thingo's from HK (turnigy). u put your radio inside a heated bag to keep your hands warm. i bought the heater thingo for another reason.. dam it gets hot!
i imagine it would go quite well.. still, that only heats your hands i guess..
I bought one, but at these temperatures it's too cold to stay out long anyways. I'm really waiting for the temperatures to go back up a bit again. Normaly during this time of the year temperatures hover at around 2 - 4 degrees celsius which is still cold but you can stand it much longer.

Meanwhile I'm working on a solution to fly out of the comfort of my home which (and here we are a little bit more back on topic) is something RangeLink with the feature of assigning the same ID to multiple transmitter modules comes in handy.

Comparing Diamond SRH771 vs stock rangelink TX antenna. Clearly see much stronger rssi with Diamond antenna.

For anyone interested, I received notification from Sid today that RL systems are in stock again. I completed my order, now just a little bit longer...

Given the way RL RSSI works (packet loss indicator rather than Rf signal strength indicator),
I'm surprised that you saw any difference at all, especially at only 1-2km. With
the antennas parallel to each other, I had periods of 100% RSSI (3.2V) all the way out at 40km with
the stock Tx antenna. I wonder if your stock antenna is damaged somehow.

Since replacing my Sanders style antenna with standard rangelink rx antenna, i haven't had a failsafe since.

Will get my friend with EZUHF to test the rangelink tx antenna. plus EZOSD has better display for signal strength!

Good to hear your failsafe issues may be behind you. Didn't make sense that you were
getting them in the first place at that distance. I'm curious though. Did you change your
stock Tx antenna *and* your Rx antennas at the same time?
