Hi,

That's a good range you have. Do you know the reason for the restricted range to the SE?

Hi viking9

Yes I know, it is due to e 40 feet high and 30 feet wide tower that fits elevator engines, wather reservoir an so on.
Antenna is jusr 25 feet away from this tower.
Unfortunatelly, it will be very difficult to get the antenna on top of the tower, since there is no way to run coax, even when, if doing so, it will be about of 120 feet long... nothing good.

Also at SW I recently have the range poored due to 5 building being built.
Theese building are 26 floor high (mine ...is only 15) and they are near 1000 feet away.

Probably till next month I will mount a Ubox + RB + 6 Dbs Collinear + ICOM PCR1500 near the SBSP, for doing the second live streaming for my site.
The streaming is composed by video screen capture of RB screen and audio from PCR1500 with the tower talking.

Also I will till next month enhance the streaming capacity because nowadays due to finacial restrictions I let it on my broadband connection with only 20 client slots.

In putting all this in a server in a datacenter, the amount of connection can be a high as 200 .... 300... 500 ...

You can enter in my site http://www.maquinasvoadoras.com.br and click RADAR.
If You are lucky to find a free slot...
If not, I let a speech from one of the aviation events here...


Cheers.
