There may be something interfering with the signal causing momentary corruption with the antenna now in its new location Markos

Alan, I hear you. I just tweaked the antenna again and changed the cable routing (I wished I had a longer cable wink, wink). Perhaps things will be back to normal again. One last question about the signal. Is it possible for a station to "hijack" a contact, or does a plane connect to any station it can reach? I mean does a plane connect to multiple stations or does it ONLY connect to the best station around? Is there a maximum of stations to which a plane can connect?

Any number of receivers can pick up an aircraft simultaneously Markos.

Alan, thanks for the feed back again. The AirNAv antenna is sitting now for the 3rd day on the 3 m pole. How are the results? Honestly disappointing. Although I am way above the sat dish, my max range has decreased by approx 70 NM and my average range by approx 40 NM. Also I already mentioned the irrational flying patterns and loss of detail on the LGSA / CHQ airport.  This is not what I expected. Perhaps the sat dish is interfering from below. I will re-attach the antenna again on my 1,4 m pole and nestle it just above the sat dish, just as it was originally placed. It would be great if my reach and detail goes up again.

Please be so kind and reset my data, as I will be putting up the smaller pole within the next two hours. Thank you in advance.

Its reset Markos.  The sat dish may be causing corruptions as you state buy you are still getting decent range although your southern coverage didn't expand as expected

Hi all,

just last week i did put my antennas 2 meters higher on a new pole. One goal was to come above a sat dish of a neighbours roof. The other goal was to get a better range. Now,  with the new pole, the range went about 25 km biger but the range of the directional antenna that was pointing to the sat dish went also about 25 km biger and lost range in the opposite dircetion. Interfering objects can increase the range to one direction. That was my experiance.

Greetings Rolf

Hi Rolf, that is what I am seeing. Now that I am back to my "old" setup, my sat dish, which is located behind the antenna, seems to propel the reach in a V shape towards the north. I have a feeling that I did not yet have found my sweet spot, as at present the pattern does not reach as far, compared to it's best. I will be working on it, haha

Hi Alan and Ingo, included in the box of the AirNav RadarBox ComStation, were 4 metal rods, probably to be used as a radial on the antenna, 3 on the side and one right on the top. I do not use them at present. Question: Does AirNav wants me to stick all of them on the antenna anyway, or should one only use them in case of a bad reception?

Markos

Those are absolutely necessary, part of the antenna's ground plane.
See a discussion here:

The metal rods are the VHF antenna

SoNic67,

the ground plane shall be at the bottom end of the antenna. The rods at the antenna discussed here were placed at the top end of the ADS-B antenna part. Therefore the 1090MHz reception was a catastrophe if the rods were mounted.
Sometimes it might be better to carefully read the whole plot before posting a comment that doesn't fit to the particular topic.

Further the antenna has an additional problem: the point were the roads should be mounted weren't water tight --> Antenna drowns if there is strong wind paired with rain which was resulting in a massive reception reduction for about 7-10days. After demounting the antenna at the end of the last year, after 1 year on the roof, I found traces of water entry at the rods mounting threads and inside the antenna. Therefore it is very good that airnav has had withdrawn from that specific antenna very quickly.

So is this one?


The concept is very interesting. Some silicon caulking can prevent the water ingress, but indeed mechanical resistance can be an issue.
And it is still for sale in their store.

I don't know if its still the same one that went out with the original comstation but that is the same as the one in the store https://www.radarbox24.com/store

Thank you for sharing Urdu News the Mexico city location. It was quite helpful

New location, North of Norway.
Not much traffic here. :/
