Hi Dunc

I've had the radarmax up for three weeks now and the attached screenshot is self-explanatory. I am usually showing 150ish in MyFlights peaking 275-300 on timeout settings of 5secs.

Just how much of this virtual doubling of performance is due to the radarmax and as opposed to simply sticking a twig in the clear above the roof apex is impossible to say of course. Still, I'm happy enough.

Interesting to see how things are for you in a few weeks. BTW I see we're reasonably close geographically.

Blimey Bratters - we don't often get completely circular polars like that.

You must be in a superb location.

Not that I know of Rod. East Midlands on the outskirts of a place called Bingham.

I suppose it's fairly flat, esp. to the east and south. Peak district north of course. I'm 110ft asl in a standard two level detached house with a 600mtr clear view across a field to the south but otherwise houses to north, east and west.

I attach an old "Hey Whats That" prediction chart I did which has turned out to be amazingly accurate. It even looks a touch conservative but that's because the Polar Diagram is built on maximums - ie flights of probably 39000-40000 feet.

I've tried to follow the tips learnt on here - box near aerial, maximum USB, minimum coax and aerial as high as poss. I failed a bit on the latter as the chimney stack is a bit iffy but overall I am very chuffed.

Well, my polar is pretty good - I'm on top of a bit of a hill, but there's a big tree to the south, and a much bigger hill to the east, so it's much lumpier than yours!

Hi John, brilliant polar diagram.   I really must get my Watsons up.

Bratters,

I live in Leicester so we are not that far away!
Before the external aerial if i had the box on for 12 hours i would be looking at approx 1200 flights with an average of about 30 on screen at once.
Today i have logged 4200 flights with not less than 130 flights on screen at any one time.
Incidentally the most was 200!
I am very very pleased so far with the aerial, i am not getting quite the range that you do but i think that is solely down to it not quite being high enough up on my chimney.
I am hoping that i will pick up a few more exotic military items now as well as all the usual C17's etc
