If possible, mount so that just the white tail end is poking outside the fuselage - one horizontal and other vertically for best results. Internally is ok too as you are not using carbon fibre, so signal loss will be minimal.
Probably a noob question, but does using a longer antenna improve range, I use 9x receivers and on most of my models the rx and antenna are inside the plane. Never had a problem and I fly my models as far as I can see them. Thinking of getting into fpv and want to put together a setup to use with 9xr and get some good rang out of it.... Keep in mind, I'm pretty new to mucking around with tx/rx's
First of all its easy to plug it in - piece of cake. Second depending from were you setup the antenna and how big is your model you make the extension. I put it as far as i can from my motor and batteries not for the range but because of the "electronic trash". I believe its the same range with this antenna but more "clean" receiver. Hope that helps
yes it can be used with that reciver and all frsky recivers... and yes you can replace only one antenna. the thin exposed end of the antenna is the part that is sending the signal. my fpv glider has two of these cum'n out the tail in a "V" shape and you can get better range that way.
hope this helps.
looking for specifically how to remove the existing antenna u'fl connector..?- 'pulling' at the existing antenna isn't good I assume..I understand you only have a couple of chances with these connectors before they fail..thanks
I notice that the new version of these come with a section at the top,(about as long as the heat shrink at the base/connector)of what MIGHT be a ferrite slug or perhaps a coil. The unshielded 31mm still exits this hard "sleeve".
I only ask in that the new five I ordered are for friends, & they NEED to pass through an "aerial tube", (similar to if it was an FM aerial)& whatever it is ,it will HAVE to be removed to "fit" (& will then look like the ones pictured above.
Realise I could cut it away, (actually I will HAVE to),but does anyone know what this heatshrink covered thing actually is?
It is not "just" the "heatshrink", it is "heatshrink" over some type of hard 'sleeve' & it would be interesting to know if it in any way improves the aerial, particularly for a more 'normal' use where it doesn't have to pass through an "aerial tube".
The heat shrink is covering the bottom half of a dipole antenna. In theory, it has slightly better "gain" than the original whip antenna (the unshielded 31mm bit on its own). However, the antenna's location within the plane will have a greater impact on reception than this minor design change will.
Does anyone know the impedance of the cable used in this antenna please? If the receiver has to have it soldered to the board then the plug is a waste of time and it would be much easier just to solder your own cable and then cut to suit the frequency. They only consist of a piece of coax with the shielding removed to suit the frequency. A dip meter should show if it's correct or not. OH! both antennas on a dual antenna system MUST be of the same length.
Agree on the length part, but in my opinion possibility to detach the antenna is very important. I had several cases when I had to change antennas. If antenna is soldered into place, it is VERY hard to do it :)
i have the fry sky module on my 9x and i noticed that the cable going to the gold plug for the areal was the same as this but shorter will this work to make it longer ( i want to put the areal wer the old 1 was not ontop of moduel
You need to have two antennas on a receiver that has two. The actual antenna is the unshielded end. These are used to conveniently locate the antenna to another place on the airplane. A short and a longer antenna would work fine as long as they are placed at 90 degree angel (the ends away from the receiver).
I don't have an FrSky tx/rx YET but was wondering if (after seeing this) are there plugs on the rx antennas? is it really as simple as unplugging one of the 2 antennas and replacing it with this? The pics don't show it so I was hoping someone who had one could let me know, if so I may add one to my order when I order my new module and rx's

BRAVO BRAVO BRAVO - CHARLIE U R ROCKING.
THERE R NO PLUGS , U HAVE TO MAKE THEM ON YOUR OWN.
The only stupid here is you. Please do the best thing you can do and disappear. So i recomend you to use your time in learn some respect and how to write correctly too (Some gramathical lessons will not kill you) Let other peopple ask and learn how to enjoy this wonderfull hobby. If you know all things, What are you doing here? HURRY UP!!! GO N.A.S.A. THEY NEED PEOPPLE LIKE YOU!!!
Macie, apart from gramathical being spelt Gramitical and peopple spelt people. I'd advise against trying to fit sockets to your receiver. Firstly they may be hard to find. secondly they may not fit the module and thirdly it's much easire to snip the old smaller antennas off and resolder the new long ones in their place. Just ensure both are the same size. Try to avoid pulling the outer covering down the inner cable. This will change the antenna's optimum frequency dramatically and detune the system.
Just to clarify, you do not need the two aerials on a 2 aerial receiver to be the same length. It is completly OK, (& I would say "normal") to just extend one of the aerials
It is worth mentioning that the 'micro connector' fitted to these longer aerials fit genuine FUTABA, FrSky for Futaba, the full range FrSkys & the 7 channel "OrangeRx R710 for $pektrum.
Of course the micro connector can be cut off & soldered to any receiver, but it is a delicate operation requiring, good eyesight, steady hands, & good soldering equipment & skills.
As said earlyer, you have to dismantle the receiver case for changing to a new antenna on the receiver. It doesn't matter if you use one short and one long, because it's only the outher end that's really antenna wire, and they are the same on all. If you are going to unplug the antenna from the receiver board, take care, and use a blade to lift off the connector, not pull it out by it's cable....this way you can use the antenna wire on a later prodject, if you rip it off, it's most possible you destroy the antenna cable inside!
Here I'm afraid I disagree. The feedline on many antennas has to be in multiples of 1/2 a wavelength. Basically what you have here is a simple dipole. The outer shield isn't exposed and pulled down to act as a ground plane (No reference to Airplane) so therefore the feedline itself is doing the job. So it must be multiples of 1/2 1 wavelength to be resonant. Unless they have devised some form of miniature antenna tuner on the board (That bit was a joke) As that appears to be the case the antenna and feedline has to stay exactly that length. Thanks for the soldering question. I never realized the receiver had a socket built in. I'm still trying to get over what I thought was a monitor. I never realized it was a monitor transmitter and receiver all in the one package. I fired mine up this evening and bound the RX etc. Amazing equipment.
