Hi all,
Just read this thread so I may be a bit late, but just my observations.
I have a GMC motorhome, the one GMC designed and built back in the 70's using the Oldsmobile Tornado front wheel drive train. It came with a 455ci engine with a quadrajet carb. (www.gmcers.org)
When I bought it in...
Hi all.
We have some Micrologix 1100 PLC's monitoring some remote equipment over an RF link using the Ethernet Port. At the Hub is a WebPort WP4520 polling each site and updating a website and emailing any alarms.
This works fine except sometimes we lose the Ethernet connection for some...
The fades can be over 25db at times and are worse in the summer and almost non-existant in the winter. The longest link is 37kms and the shortest is 22km.
Of course with digital you can't just "listen" to the signal like go ole analogue.
These are also licenced fixed frequency (full duplex)so I...
Hi
I could mount the entire antenna at a 45deg angle at both ends if it would help, but I'm not understanding why giving the antenna polarization a tilt would help.
I understand that circular polarization will help since the mulitpath is likely to be in the opposite direction, however I can't...
Hi
Thanks for you reply
There are actually 6 links in star formation, each at various heights at hub depending on the lay of the land to the remote sites. The remote sites are mostly on water towers (about 40+m high each) since this is a municipal owned radio system.
Some link antennas are...
Hi all
I have some licenced 900Mhz digital links that randomly fade or cut in and out, usually during the night/early morning. I'm thinking its multipath from atmospheric conditions. Sometimes the signal level will fade, other times there will be good signal but the SNR will drop.
I have...
