Hi Folks,

I did a search on this topic, but did not find any specific results on this subject in this forum.

I have recently purchased a new WiFi Booster for my Turnigy 9X radio. I have installed it on my radio and following are a few pics. The idea is to increase the 2.4 Ghz range and I believe these boosters are good in doing so. I have read about these boosters being used by many people in other RC forums, so I though I will give it a try to fly long range FPV using my existing 2.4 Ghz Radio. Similar boosters are available on ebay and here as well... http://www.rangevideo.com/index.php?main_page=product_info&cPath=62&products_id=245

I bought it from a guy on ebay.in from Chandigarh. Got it for INR 2700 (1 Watt, Made in Taiwan)
Using the Tx battery pack for powering the booster with a HK UBEC at 5V, 3A.

Yes, it consumes quite a bit of my Tx Battery power and also becomes pretty warm. I am using 2100 mah Eneloops. And it gives me 1 hour of continuous operation with a fully charged pack. Ground checks are really impressive. It even knocks of my Bluetooth connection from phone to headset. Giggle

Will be testing this setup on Jan 26, 2012 with my HK EPP FPV and FY31AP.  Grin

Retreat, Hell!



Is it like 'plug-n-play'? No soldering? I mean do we have to connect just supply wires and antenna wire and nothing else?

Yes... Just PLUG and PLAY  Grin Soldering required only for the power supply, if you wish to power from tx supply. Else you can use a separate Lipo. Then NO SOLDERING required.

I realised later that I could have mounted the amplifier on the top of the SMA connector itself without using the supplied cable. The amp can connect directly to the SMA connector. However, that would have increased the height of the Tx and disturbed the balance of the tx... and moreover I did not want the weight of the amp to be loaded just on the SMA connector alone.  Wink

Hi Saurabh,

Good luck with your next long range F*V venture. Here is mine done a while ago.

http://www.rcindia.org/radios-and-receivers/extending-range-of-a-futaba-2-4-ghz-radio/25/

However I had to replace the stock antenna with SMA Pig tail to take RF out for the Booster. Did your Turnigy 9X come with SMA mount for the Antenna?

Hey Saurabh, why dont you rout the SMA cable from the same hole where you popped out the power cable ?You can also put a Heat shrink to house the power and RF cable together.  Its easy for the cable to become faulty at the SMA connector over the time.

Looking forward for good review.... all the best for the Re-maiden....

Hi Sundaram. No Turnigy 9x does not come with sma connector. I have the FrSky DIY installed that comes with that connector. The supplied cable is not long enough to reach inside the tx, hence this setup. I saw your modification as well. Howz the performance? With my setup, i am expecting atleast a 5 to 6km or more. Lets see this thursday... Will keep it posted.

Supposed to be much more than 5-6 kms. With patch antenna it is supposed to be close to 20Kms line of sight. Being hills never really dared to verture far.

Hhmmm... I agree... I was a little conservative while quoting 5-6 kms...  Evil
I knw with LOS it should reach close to 12-14 kms. But I do not have a plane with that endurance..  Wink . To fly 5 km, your plane should have an endurance to fly that far and then return back home..... However my hk epp fpv does have enough power to go upto 4 km and back...  Smiley

Vineet, i have not tested the ground range as of yet. But I know for sure that it is strong enough to kick off my bluetooth connection... Never had such an experience...

The blue tx balancer is from HK. Search for neckstrap balancer for 10 channel or more on HK

what is the range of your video tx? The task of increasing the vidoe range is more challenging than increasing the Radio range.
I am feeling limited with my video tx range.Last week I did ground test of my fpv setup.. Will update in a separate post..

Thanks Ujjawaana. As said earlier, the cable is not long enough... Will let you knw bout the results. Thanks for your good wishes.


You can get a U. FL to SMA-Male cable, which come in both 6 and 12 inches lengths. the 6 inch one is just $3 inc shipping.

http://www.ebay.com/itm/New-6inch-U-FL-SMA-Male-Straight-Bulkhead-Pigtail-/300654148583?pt=LH_DefaultDomain_0&hash=item4600623be7#ht_1860wt_957

You can remove the U. FL cable from the RF board which goes to the front of the Tx. Directly connecting the AMP to the RF board would give you lesser attenuation (one less connector) and more reliable link. Just dont forget to put some Hot Glue to stick the cable to the board near the  U.FL connector so that the connector does not move.

Anyone know if this would fit the Aurora 9?
Can it also be made to fit the Tx for a RC car?

U can use the booster to boost the range of any RC system that works on 2.4Ghz (it does not matter if it is land rc or air rc)
Any frequescy between 2400mhz and 2500mhz will work. However be careful as this is the microwave range. Keep it away from your body as much possible, specially from your head Wink

NOTE to ADMIN.

Request to please merge this topic with the existing thread or vice versa "Extending Range of a Futaba 2.4 Ghz Radio".

I dont see a point having 2 threads for the same topic.

Thanks.

saruabh, where did you pick the 12v out from turnigy board? I dont want to get it from the battery directly as I am forgetting to remove the the connection to booster when I switch off the transmitter.
I want to get the switched voltage from board so that booster is off when I switch off transmitter.

Hey Foamy,

When you open the turnigy tx. Look for the back side panel. You will see the following pins. See the pic for details.
