    Hey,

    I have my FPV setup completed and have been testing it for a few days. However I get some pretty bad interference at even "close" range of 100m. I have a Boscam TS352 TX 500mw and a Lilliput 329W 7" Super FPV Monitor with a built in antenna.

    The video get flickerish and even looses color at some point. This got me thinking about adding another Antenna on the receiver end or get 2 replacement antennas.

    This would be an option too I guess: http://www.helipal.com/5-8ghz-flat-panel-super-long-range-antenna-male-receptacle-14dbi.html

    What do you guys say?

    If I'm not mistaken, your monitor/receiver only accepts a single antenna. Generally, it's recommended to use a monitor with a diversity receiver that accepts two antennas. In diversity mode, the receiver will automatically choose to use the antenna with the stronger signal.

    Two popular monitors with built-in diversity receivers are the Black Pearl rc801 and Boscam RX-LCD5802. With a diversity receiver, you can then replace the stock rubber duck antennas with an omnidirectional (short range) and a directional (long range) such as those from FPVLR.com

    This is a highly recommended bundle: http://fpvlr.com/shop/index.php?route=p ... uct_id=106

    You are right its a single antenna device :/ I got it with a helipal bundel.

    That sucks. Any other way to improve the signal ? I mean the transmitter should be powerful enough.

    Thanks! I will consider doing this! Need to step back with my spendings on this hobby for a while tho, spent way too much lately ;)

    The fpvlr website doesn´t load for me too.

    I had *mild* improvement with these cheap antennas: http://smile.amazon.com/NEEWER-Circular ... B00GLJ7UVQ

    I was just too impatient to save up for the FPVLR antennas, which are vastly better. But if you're on a budget, these may help. Before ordering, confirm what connectors you need. These are SMA male antennas.

    Or here, these have better reviews and are relatively cheap: http://smile.amazon.com/Shipped-Cheap-D ... YXJKWFAZ41

    My opinion, though. Save up for a diversity monitor/receiver and FPVLR antennas.

    If you only have one antenna input, replacing it with a high gain antenna, will do more for you than increasing the power output from your video transmitter.

    Which one should I get then ? I would rather spend more money on one antenna than 2 for both sides.

    yea you really don't NEED a "diversity" receiver IF you get a super nice antenna. I personally recommend the FPVLR 4.25 turn helix. it's directional so you'll need to keep it pointed in the direction of the Phantom during flight, but it's amazing and it's capabilities far exceed the range of the P2 itself.

    that being said, having a good transmit antenna is also important.. if your transmit antenna isn't any good then it doesn't matter how good your equipment on the ground is. but sure, start with the helix and if you wind up needing to upgrade the transmit antenna, then do it.

    I've run a TS352 before although now I'm on a TS353 because it's lighter and with my FPVLR antennas I get perfectly good range (1.5-2km easy) without needing that extra weight and power.
