Usually ready in 1 hour

We are excited to bring to you in one package deal all of the antennas and pigtails our friend Richard Sisco used in his special YouTube video tutorial showing a do-it-yourself antenna modification process for the DJI Phantom 3 Standard Quadcopter drone.

He uses 1 ALFA APA-M25 and 2 ALFA APA-M04 Wi-Fi antennas to complete the modification as well as 3 RG178 IPX U.FL BS1 pigtails that are 8 inches long.

This kit here includes all of these items. You get 1 APA-M25, 2 APA-M04 antennas, and 3 pigtails. Note per Richard's instructions in the YouTube video, you will need some additional tools, epoxy, etc. to complete the mod. Go to the direct YouTube page to watch the video and review the video description for full instructions. This kit does not include those types of things, this just includes the antennas and pigtails you need to buy for the mod.

Directional Antennas
The ALFA APA-M04 and APA-M25 antennas are both directional. Directional antennas concentrate gain in a particular direction and are excellent for using with drones. While the antenna does not need to be in a perfect line of sight to the signal, it needs to be pointed in the general direction. The ALFA logo side of the antennas should be aimed in the direction you are trying to transmit or receive.

Connector A: RP.SMA female, Gold plating
Connector B: IPX U.fl female, Gold plating
Cable: RG178

Customer Reviews

Very Satisfied

I give the product itself a five star rating, it's a great product at half the price of the competitors! However, Overall, I have to rate the overall experience at 4 stars due to the installation process and pretty much the absolute worst tutorial video imaginable via youtube.
With zero audio and snap shots of the step by step process that aren't very informative or detailed and fly by way too fast for someone trying to figure out the installation methods, I found it to be pretty much useless. After installing the anttena's on my own and then reviewing the video, it made alot more sense, but I can imagine the frustration someone might encounter if they aren't very inclined at this sort of thing. The other reason I give a 4 star rating is the lack of a better means to secure the center anttena. I don't think it would be very difficult to develope some sort of an adapter to mount the antenna in this position. The fact that you're left with no other option that to squirt some JB Weld on the joint to hold it in place makes it feel kinda cheap and jury rigged. Other than that it's a great product.

Thank you

Wish it would have gave me more range but it is easy to use it and install so good

Beyond belief

I’ve watched a ton of YouTube videos on expanding the range of my phantom 3 standard. I’ve ordered and installed at least three different ones including 4hawks etc. The other ones did extend the range some. But I could never get past the 3000 ft mark. I’m flying over a picked corn field with zero interference. Different heights and directional changes etc. I decided to buy one more set of antennas and give them a go. These antennas specifically from this website are THE BEST THING I’ve ever tried. On my first go it was able to reach out to 6000 feet with 3-4 bars of rc reception left. This was also in high fog and very wet conditions. Not ideal at all. These things are too amazing. I’m not sure I could reach 14000 feet, but by what I was getting before I bet I could get darn close!
