Patch straight up for overhead flying?
« on: June 02, 2017, 10:40:43 PM »

I've got a dual Rx which has one skew and one Immersion mini patch.
Once I get bignose skews on the plane and rx distance won't be an issue.

What I find weird tho is my rx seems to never want to swap to the patch, even at a distance when it's getting fuzzy and I'm looking in the right direction.
Swapping the aerials it'll still pick the anomway skew unless I cover it with my hand.
The image when swapped to the patch is fine.

So am I wasting my time hoping it'll swap to the patch at a distance, at which point the signal is probably so bad the patch isn't going to be an improvement anyway.

Is it worth removing the extension and 90 from the patch and screw it on pointing straight up?
The skews have a null zone vertically so cloud surfing up above the field would the patch do a better job above me?

I'm imagining I'll have a zone a bit like a pineapple with the two working together.

Or would I do better bending one of a pair of skews over on the Rx so it's nulls are horizontal?

Cheers

When the Skew picture gets ropey the ex5 should swap to the patch antenna which should be crystal clear for many in more unless you have a poor patch lead or something wrong with the patch antenna like a bad soldered joint or using the wrong polarisation.

I've tried without the lead, just a 90 to aim it forwards, no difference.
If I blank the skew with my hand to make it swap the image quality seems about the same for the same sort of distance.
It doesn't seem to have any advantage.

On the other hand I can improve my image by moving my head around more accurately when at distance which makes me think maybe it has swapped as the skew shouldn't be directional.
But sometimes that movement might not be looking at the planes direction.
While a head move can improve the image, it doesn't vastly change the range, the image will soon break up again, it doesn't appear to vastly outperform the anomway skews.

I've not asked someone to look at the indicator when I've been out that far.
Maybe I should try a few more tests.

The only other test I've done is to tune into a friends plane to see how good his Bignose skew was on his plane, my rx set up remained the same, anomway skew and the mini patch.
I more than doubled my range and with head movement and had better image quality at times than his ground station which was sort of pointing in the right direction.
He had a Bignose skew and fullsize patch.
