How far away from your location is the airport and at what altitude are the aircraft just before you lose contact?

How far away from your location is the airport

at what altitude are the aircraft just before you lose contact?

Thanks.

Send me a PM with your location coordinates in degrees decimal and the name of the airport where you are tracking aircraft landing that you lose at 13,000 feet.

Last chance before I give it away

If any one is close to an obstruction and UK based as long as they give a review of the findings I will send a beam out to them.
I only have one so first to email me with Forum Name and name and address  chris.taylor@taylormaderf.co.uk will get it with my compliments (UK mainland only unless you want to pay the carriage)

I have now given the antenna away !

Hi... as before stated... if you have obstructions... no way out, but i made this 11 elemts yagi only to check if it will catch better signals from SBGR ground. I live at a place 9 NM from SBGR.. and did not noticed much better performance with this Yagi.
Very, very cheap and easy tu build.
Got the data/calculation from : http://www.k7mem.com/Electronic_Notebook/antennas/yagi_vhf.html

Best regards - Juan

So i get my cheap 25€ Chinese Yagi Antenna and the expensive 150€ special Antenna.
Is there any measurement software who allow me to compare the Antenna?
Thanks

Probably best way is to test them together, pointing in the same direction and conected each to a similar receiver a dongle for example, receiving the same aircraft at the same time and see for yourself which one receives better, make sure you interchange the receivers to make sure one is not at fault, for less than 20€ for 2 dongles you can do the test.
