Re: Nautel V15 GE power supply failure

I've had that answer from the best of companies, just depends who you get on the phone. They will go down the list of everything that you could possibly do wrong. Never offering something that is on their side of the fence.

Re: Connector suppliers....

Beware of the new Andrew cable - the copper sheath is very thin and you have to be extra careful that you don't cut through it when installing grounding kits. The center conductor is also thin and filled with foam to try to make up for the fragility of the conductors. I would stay away from it. Thi...

Re: USB Keyboards/Mice for Studio

I've been using HP mice with good results. I know a lot of HP stuff isn't that good, but the mouse they sell at Best Buy runs with no problem . The batteries seem to last forever, well over a year. Give one a try. These are wireless of course.

Re: Connector suppliers....

SWR has a line of connectors a bit cheaper than the other boys, and I think the quality is just as good.

Re: Can´t receive sat freq over 11500 V or H

I would say use the largest dish you have preferably offset focus rather than prime focus. also is it possible to ground mount the dish? High rooftop dishes are more prone to interference. Maybe try to position the dish on the side of your building that would shadow it from the interfering source.

Re: Convert to LEDs, or leave 110v?

Why not just use a commonly available 110v. LED bulb screws right into your existing socket.

Re: Weatherized cable/antenna identification tags

You can get customized dog/cat tags engraved at pet supply stores for less than $10. They are aluminum and will last a long time.
Good idea to tag all that stuff.

Re: Chain link fence

We used sizable pre-fab dog pens at the base of our towers. Easy and cost effective. Tied into the ground system at four points. Never had any problems. You can always add extra grounding later as needed.

Re: Burk ARC-16 ESI Card

I had a problem similar to yours on a ESI. I found the low value resistors (10 ohms I think) right at the input to the phone line had gone high in value, probably from a surge. Check those.
