Improvement of Coverage with new antenna

Hi,
I was curious about the performance increase I would get by using an antenna such as this one: https://www.ebay.co.uk/itm/Antenna-ads-b-collinear-1090mhz-white-great-gain-COL1090-5-H-Vinnant/292859256079?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908103841%26meid%3D4730da3feffc41078b68ce474984617f%26pid%3D100227%26rk%3D2%26rkt%3D6%26sd%3D123346374741%26itm%3D292859256079&_trksid=p2054502.c100227.m3827

I’m currently using a small cheap one of modmypi: https://www.modmypi.com/raspberry-pi/communication-1068/3dbi-ads-b-1090mhz-sma-antenna-w-magnetic-base

Thanks

hi I bought one of those 6 month ago, and hilst it is only mounted in my front windo, I regular get upto 200nm and it seems to do all I want as I am located on NWEngland just short of scotland I catch a lot of north south taffic


hope this helps you decide,

this is what i get currently, it doesn’t seem to be much better…: http://prntscr.com/lxkat6

Most likely it’s gonna be an improvement. How much of an improvement depends on your dongle and if you have hills near you which would block the view.

If the horizon is basically at your elevation and the antenna has a clear view it will most likely be an improvement.

Anyway i don’t know the quality of the antenna so it is hard to tell.
But pretty much everything is an upgrade over unmodified magbase antennas.

Why don’t you check on your radio horizon, see this thread:
(What is the Maximum Range I can Get?)

Newcomer here, so this may have been noted before, somewhere.

Been experimenting for a few weeks to make sure my set-up is stable.

Originally started on 11 Dec 2018 with the NooElec ADS-B Discovery 5dBi (High Gain) Antenna 1090MHz

After changing over to the Flight Aware 1090MHz antenna


with a short (1m) cable, in the same position (antenna elevation 38m).

at c 1100 UTC on 27 Dec 2018 produced a leap in performance:

  • from average 5 position reports on a screen, to 50
  • from average 5 mlat syncs reports to 442
  • from range of <50 mi to over 200 mi.

Next plan is to put the whole setup in the loft, in the new year.

Hope this helps.
