Grounding dishes/antennas

Whilst the codes are clear http://www.satelliteguys.us/free-ai...s-your-switchbox-look-like-5.html#post2062603 they appear to have been written for Cband, DN annd DTV where the dish itself has a direct connection to the coax shield.
However with FTA where this is rarely the case, as LNBs and their holders are plastic. I think the European method of additionally grounding the dishes themselves locally to be more appropriate. Since there is then no ground connection to the house ground there would be no ground looping involved.
Actually the idea of the coax doubling as part of the lightning conductor route is a alien to me.
Perhaps like European codes this is covered in another unrelated chapter.

I've always considered it to be a good idea to ground the antenna to it's own ground rod. If I recall correctly, this is required in a lot of local codes. I have my TV antenna tower and my ham radio tower grounded, also. I work with terrestrial microwave radio and Ku sat up/down links, also, and all of our towers and fixed satellite antennas are grounded including any guy wires. I highly recommend grounding antennas - it might just save your electronics from a nearby lightning strike (rarely does anything survive a direct lightning strike, though). There are coax surge suppressors that would help also.

This all started when I realigned a dish that actually had a plastic mount on to its pole clamp. I took this up with Mike Holt and he and his collegue replied to the effect the code needs amendments and they will work on this.
Pendragon it seems the code is for static discharge as opposed to lightning. Remote grounding , shortest path is definately the way to go and personally I would not take a ground back to the service ground to prevent ground loop impedance.
In Cyprus we do have lightning storms without any rain so a good local ground is important. When I can find the secure place I put the photo of a aluminum 3m dish hit by lightning Iwill post it.

I don't think the code cares much about static discharge. It seems mostly concerned with ensuring the mains ground is consistent.

When I was in college I worked as a chief engineer at several broadcast facilities, and separately ran a large sound reinforcement company. It was interesting to see how different the perspectives were with grounding. In RF everything was grounded everywhere and separately bonded together, although the latter not always that well. It was very safe, but there were ground loops everywhere and this was a constant source of audio/video problems.

In sound reinforcement, whether indoors or out, the name of the game was to have one hard ground to which everything had one path to minimize mains noise. But during outdoor festivals it was easy to have a system spread out well over a 100m diameter and talent/crowd safety was a major concern. Things are a little different today, but back then one could have dozens of µV-level microphone lines running from the stage back to the mixing desk alongside speaker amps pushing 100-200V on their outputs. With that much system gain it seemed amazing that anything worked at all.

This school of hard knocks taught me a lot. For safety's sake I had to live with multiple localized grounds. For ground-loop sake, I needed to minimize return paths and ensure the bonding between the local grounds was overwhelmingly low in impedance. It was a lot of extra work, but in time I cleaned up the broadcast facilities and got the sound reinforcement methodology tuned to the point that mains noise was inaudible directly at the main speaker stacks. Grounding often looks like magic, but really is just meticulous engineering.

However the 17 gauge steel messenger wire requirement is in the code and seems to be only for static discharge. It certainly would not be big enough for safety.

When I was in college, I participated in a small times research project that actually provided a good grounding in my future profession. :)

Song Name Game Part 3!

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!

So let the game continue!

The last song was added by Bobby who posted...

One Meat Ball - Andrews Sisters

CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!

Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game

Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.

Example:

Long Live Rock and Roll -- Rainbow

Rainbow in the Dark -- Dio

Another example:

Ride the Lightning -- Metallica

Lightning Strikes -- Ozzy Osbourne


Get it?


An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....

Finished season 3 last night. Still one of my favorite shows.

Anyone else wonder if there might be something else going on with Callum? Seems to me he has too much access to Russian intelligence.

Hopper 3 with Hopper plus internet connection problems

Over the past few weeks, I have had problems connecting to streaming services (Netflix, HBO et al). When I go to the TV's native Channels, I have no problem. The Dish internet troubleshooter shows I have a good internet connection. I'm wondering whether it's an issue with my internet provider or a problem with the Dish software on the Hopper Plus. Anyone else seeing this?

I have a DISH Hopper 3 (Software H713) with Hopper Plus (Software P15403). I have not tried streaming services but I primarily watch TVB Jadeworld international package which is only available by streaming and when I have an issue, I usually have to go to a non-streaming satellite channel first before the streaming channels will work again. What software versions do you have and what is the error message if any are showing on your screen? or is that Dish downloading logo just stuck and never finishes?

I'm on H713 on the Hopper and P15403 on the Hopper Plus. It shows internet connection issues and doesn't finish loading the various services. I see the "loading circle going around. Sometimes I get a message saying that the service is having trouble loading my content and to check the internet connection.

Did it ever work correctly before? Hard to say what the problem is. Usually for streaming, it will show the Dish logo with lines sweeping down to show downloading, never seen the circle issue. Did you try a manual reboot, red button reset, power cord unplug/replug to see if it makes a difference.

Might be worth just to ditch the hopper plus. No issues here on h713

Buy a roku and dump the hopper plus you'll be better off. If you have a smart tv you don't need either one. No hopper plus here and no issues!!!
