    If you have done a wifi extender amplifier mod, please post and discuss here. I would like to see your setups and ranges achieved by amps.

    I used a 2watt sunhans amp, works great and adds no less than 50℅ improvement in range maybe as much as double. I have not tested it to its full potential yet.

    Just take the pigtail out of the extender
    Put an attenuator on it and into the amp
    The other side connects to antenna
    And you have to power the amp with external battery

    Just ordered a 4watt amp and a 14db TP-Link Tl-Ant2414A antenna. Will let you know as soon as the parts arrive.

    ok, whats the reason behind the coaxial attentuator? is it so you dont overpower your antennas?

    Ok most the amps are 20 dbm input or lower the one I posted a link of actually says it has a chip upgrade to accept 26 dbm input
    Meaning the input power to the amp
    So with that amp you technically wouldn't need the attenuator
    The output power of our extenders is around 21 dbm. so it's over the max input of "most" amps on the market
    The attenuator just lowers the input power by 6 dbm to make it safer for your amp
    I know someone on here is running one without the attenuator

    ok, what types of ranges do you expect to see with your setup?

    Under normal conditions
    4 times the power = doubles your distance
    I got a 2w amp
    The stock output is around 126mw
    So 15 times stock power
    Should over triple my range
    But distances vary depending on antenna types and location power levels out of the pv2 all kinds of stuff
    To add I'm not really trying to beat a distance record I just want to be able to fly through some more trees as I live in the woods

    Here's the video showing how to make the connections of a Sunhans amp to you modified P2V range extender
    http://www.youtube.com/watch?v=7tUW6pg5zwc

    I have to say it works really really well. Adds no less than 50% range if not double the range as opposed to without it. With the Sunhans powered off of a USB 2amp power source I did a quick test flight this evening at around 850 feet high and over 2,000 feet away with the 640x480 30fps preview option in the new DJI application, though my vision is on the 2.0 firmware. The wifi feed was always at full signal. The video feed was flawless, it didn't cut out once and the meter always showed full signal. I flew from my back yard which had about as much wifi interference as you can get yet had these great results.

    I was using a Circular Wireless 11dbi RHCP Helical, and 2 circular wireless 2.3dbi RHCP Skew Planer antennas on my Phantom.

    a few days ago I flew through 2 batteries and the amp did not get hot at all that I can tell. It works very well.
