Can I use this antenna as an extension for a FrSky V8R4-II 2.4Ghz 4CH Receiver. I am building a sloper where the Rx will be encased inside. I'd like to lengthen the antenna to lead it outside the fuse.

No you cannot use this one, the antenna is accorded to the frequency range, and this one is made for 2.4 GHz.

Tip: Shorten exposed (non shielded) end of these to 19mm to double your range. Or, and even better, solder another 19mm piece of wire to the shield and make it a 1/2 wave dipole. This will triple your range.

What?! Don't post such misleading instructions. I don't discuss about the dipole idea. But I've ordered this product and I've measured the exposed part length to 32 mm, which is a quarter of wavelength in the 2.4 GHz bandwidth. There is no way to "double" the range by cutting the wire, unless it has been terribly bad manufactured and goes far beyond 32 mm. Doubling the range requires a 6 dB gain, which would need an amplifier or a more focused antenna, which you wouldn't want to use on an airframe. Please, nobody follows what he said and cut the length of the wire, unless you know what you're doing.

I'm so sorry to say 19mm. Don't know what I was thinking. I meant to say cut exposed end to 29mm because 32mm is not correct length for best performance. Same with the dipole wire. It does make a HUGE difference in range. Instructions for constructing the half wave dipole are easy to find on the web. Again, sorry for the confusion.

I prefer this *) If the transmission is better with a 29 mm antenna, it is maybe because the receiver exposes some unshielded parts of the antenna over a few millimeters on the internal circuit board. Which receiver are you using? Also what is the max range you obtained?

BuBu, search google for this: "Half Wave Straight Dipole 2.4Ghz FrSky Build". You'll see an RCGroups discussion. All info and results are in that discussion. I get similar results. I usually use the D8R-XP because I use RSSI and CPPM www.link to RC

I bought couple of thees. It is useful to replace broken antenna of frsky receiver. The distance shortens very much with broken antenna.

This antenna is a real upgrade and should be standard equipped with the Telemetry tx.

Another great accessory from HK, cheaper then WiFi replacement parts. I was waintig for that. This kind of antenna is easy to break on plane crashes so it is a good idea to have spares available.
