Antenna for 2.4Ghz 11dBi Omnidirectional

 Casper 72 points

sí* funciona con el mó*dulo FrSky pero tiene una "mujer a mujer" conector. pero la pró*xima vez que quiera saber algo só*lo pregunta en Inglé*s se puede traducir con el traductor Google. Lo he hecho lo mejor no muy corregir el texto.

 Casper 72 points

i wanted to connect it to my corona module but this antenna is RP-SMA so you have to buy an RP-SMA to SMA connector (corona is just an other company but it works the same as FrSky)

If I understnd, I can yes?

 Casper 72 points

yes you can use it for the FrSky module but you may need this: *******www[dot]ebay[dot]com www.link you need an SMA female to SMA female connector to use it for FrSky modules

 Andrzej 336 points

Thanks

 Casper 72 points

I made the mistake with my module :)just check if you need the female to female connector.

Hi there, 'omnidirectional' means that it operates from all around, rather than 'directional' (such as PRODUCT ID: BY-2400-12) can operate from (more or less) straight in front. Whilst a higher gain antenna (the ??dBi part) may have more reach, the trade off is a more narrow footprint than a lower gain one. ie 3dBi antenna found on WiFi routers, and R/C transmitters, etc, has a footprint that is very much all around the antenna. Google "ANTENNA GAIN EXPLAINED", there is a good article there on ZCGdotCOMdotAU that explains it simply. (it's about mobile phones and UHF radios, but radio waves are radio waves, whatever the frequency). Hope this helps.

Don´t use it for boosting a 2.4 GHz RC Transmitter, as it has high gain, it has not good omnidirectional coverage - it is good for FPV 2.4 GHz Video Receivers, though.

 Peter 17 points

If you use the antenna on the Video-RX and set it up vertical (plane: vertical, too), it will receive well if you do not fly too high, but around you.

 gIMpYchUM 5 points

If it is vertical it will work well on the sides of you but not directly over the top of the antenna. Most omnidirctional antennas have a radiation pattern that looks like a donut with dead areas directly above and below the antenna. type in radiation pattern onmidirectianal antenna into google if you would like to see a video of what i am talking about. *******vimeo****/8826952

Either will work...

This antenna connect to the RX for FPV.

*900mhz antenna

 greengo746 45 points

This will work for 2.4ghz. Antenna are designed based on their frequency requirement. If you want to use 900mhz system, do look for 900mhz antenna that is hard to find on the market. For easy to buy antenna, use 2.4 or 5.8 ghz

Adding a little more... I wouldn't trust just the RX w/sat RX to get 2 miles. For a more solid link, get this antenna. Line-of-sight flying can get 10,000 feet, but FPV is almost never LOS, so that's where the bigger antenna needs to step in. Even with the larger antenna, you may only get 1.5 miles range. Another option would be to buy a 1 watt WiFi booster for about $50 on eBay or RangeVideo, and that'll give you a TON more range... like 5 miles plus. But, if you need real long range, just spend some good cash and get a nice UHF like Dragonlink or EzUHF. I've heard multiple problems with those WiFi boosters.

Hobbyking blocks links... you have to put the **** like (dot)com for it to show up. Are you on any forums? I'm DJO on RC Groups, you can contact me there.

i will add you now to my rcgroups! i am ""Air Heros (juan) ""

 Mikhail 18 points

ofcourse it will, but check the connector type in your TX module first.

 Heppy Ket 401 points

Absolutely not, if you blow your output stage then range will be ZERO. Be very careful when messing around with transmitter aerials, do some research (check out IBCrazy on RC Groups). The aerial your tx comes with is often the optimum. To improve range try the receiver first, but again, know what you are doing.

 Lazuri 7 points

this antenna is for 2400MHz. So you cannot use 900MHz system.

 Heppy Ket 401 points

Q1 Yes. Q2 Yes. But you should research antenna's some more check out ibcrazy on rcgroups. Big dbi numbers (like watts) aren't everything.

 greengo746 45 points

ibcrazy antenna design is more to video downlink. big dbi numbers = directional. Depends on your flying style, u can use patch antenna on tx and this antenna on rx but 11dbi is very wide. U cant fly high above you but you can fly far away.

 Heppy Ket 401 points

So long as all the "wiring" hooks up correctly, can't see why not.

 greengo746 45 points

it will work but not as advertised. this is because 5.8ghz need a shorter antenna. U need specific frequency antenna to work at your frequency in order to maximize range.

 Heppy Ket 401 points

Not advised, you are best using an antenna designed for the band you are in. A multiple can sometimes be used, but 5.8 is not a multiple of 2.4, find something more appropriate.

 RC Fabiuz 8 points

it work not well. you must buy a 5.8ghz antenna

 _JeaN_ 110 points

esta e uma antena de recepcao usada em kits fpv e nao uma antena de transmisao. se vc quiser procura se informar para fazeri isto mas da certo sim se vc colocar uma antena de transmisao boa pode aumentar o ganho do rx.

 BigCoinCoin 9 points

More than 2 km with a 500mW transmitter. I did it.

 krtek2k 106 points

Yes, why not. It has bigger gain , then original antenna. Only thing is , if you can connect it to your TX.

 Nico123 51 points

No, this is a receiving antenna, not for transmitting!
You will damage your transmitter.

 dps-dave 205 points

Hi if i'm correct in thinking will this sit or mount on a car then the answer is yes as long as tx will allow for a sma connector. But why as a 2 or 3 dbi would work much better ?
The more or higher the dbi doesn't mean to say the better the range

thanks Dave uk

 lcs186kmps 49 points

Hi there, yes it will work very well as it is meant to be used for the 2.4ghz frequency band, it will give you longer range for you transmitter because of the 11dbi rating which amplifys the transmitter power by 11 decibels, for every 1 decibel increase in the rating of the antenna the power output of the transmitter is doubled. hope this helps you cheers

 paintballkidz 26 points

A higher gain antennas beam will be more narrow, a 3dbi will have move of a globe beam where as 11dbi be will be more like a flat circular plate.

 hotzenplotz 230 points

Hallo Nico123 Wenn du keine Ahnung hast dann schreib lieber nichts und nicht so einen schwachsinn. Die Antenne arbeitet sehrwohl als Sendeantenne habe sie seit 4 Monaten an einem FrSky Modul im Einsatz und habe damit die doppelte Reichweite.

 Dragevo 606 points

Yes, the base is magnetic.

 wchiro 188 points

Just received mine....Yes it is!

 dps-dave 205 points

Yeah 1/2" over so its 12 1/2" overall

 EatAtJoes 780 points

This is why you get return to home setups, that way loss of signal sees that your plane comes back to you and stays in a kind of holding pattern above you. This is achieved with the Eagle Tree OSD Prod and the FMA Co=Pilot II together this ensures a safe trip, search on youtube and you will see what I mean. I have that exact setup here and its really nice... There is also a forum dedicated to return To Home setups on RCGRoups.

EagleEyes is in stock now. Got an email couple minutes ago.

 SBAlv 96 points

Thanks Asad, just got mine after long time waiting.

 __Asad 2519 points

Cheers!

 Dragevo 606 points

Ok, 11 dBi. They just updated the specs.

 EatAtJoes 780 points

The problem is the antenna lead is too long, 1M with that size coax has quite a bit of loss associated with it, the best would be a connector at the base of the whip itself, this is the same for any antenna like this, my antenna leads are as thick as my thumb with very little loss

 EatAtJoes 780 points

although not clear it would appear that the whip can be removed from the base which would be ideal, think of it this way, no lead = no loss, its that simple. (sorry about that it's just the Electrical Engineer in me popping out to voice) Also do not have 2.4GHz video with a 2.4GHz radio, they dont mix... 5.8GHz video is the way for people with 2.4GHz radios

 SBAlv 96 points

or 900MHz (where allowed). That's what I use, although I am very tempted to try a 5.8GHz setup to get a less radio-polluted environment. Any one of you guys have experience with a 5.8 GHz system?

 gamman 7 points

you can also use it on a 2.4GHz TX as well!!!

 EatAtJoes 780 points

Good point to using it on the TX... never thought about that, but you need to be aware of 1 thing and that is the higher the DB in a whip antenna the more the pattern of signal will look like a plate (picture a plate) really strong along that plate but above weak, tilting the plate loss of signal, this happens more so in 24db antennas than 11db a 24db antenna you would almost have to be at 90deg to the model at all times but 11db is more forgiving in that respect the pattern ends up looking more like a squashed tennis ball but does not go out as far as the plate pattern. The more you concentrate a signal into an area / spot the less forgiving it is outside that pattern. Thats why radio's have 5 - 7 db antennas on them so they work at all angles

hey,
can i use this to increase the range of my Turnigy 9X Tx?

 n3m1s1s 1021 points

yes as long as you understand the principles in the post above yours *) ie vertical orientated antenna goes far but not high so to to go high but not far simply mount antenna on the horizontal plain *) mount rx antenna the same as tx and your good to go *) i use 11dbi on my 9x
