Just wondered . I have no noise where I fly and the mavic will go what it says under 200 ' with full signal stock. Everything has to be right though like no wind not to hot just the regular stuff . Really don't know what it would do in a urban area . Wouldn't try anyway .
Are you flying on 5.8Ghz AUTO? That's the secret to distance, against expectations that 2.4Ghz work better.....because it doesn't. I can easily exceed 3 miles with a windsurfer on 5.8Ghz. Gadget guy goes beyond 4mi over suburban San Diego all day long, but you need LOS connection. No trees, buildings or mountains between your RC and the craft.
Oh yeah, they work great, almost as good as a $130 DBS2 Itelite directional antenna. The key advantage is this doesn't alter the RC so warranty isn't affected, unlike with a Itelite antenna that a modification to the radio, not to mention it stores easier in a backpack. Great value. If you use Litchi, which displays signal percentage instead of bars, you can see how much it improves signal by hovering a mile away, then remove the windsurfer and put it back on. Works very good.
