Re: [WISPA] Direct TV interference from 802.11b client?
That's good stuff. I wonder why we are still running two coax' on all of our installs. Gotta ask our DTV trainers about that.

Re: [WISPA] Direct TV interference from 802.11b client?
The IF frequency between the TV dish and the TV receiver is a lower frequency. Not sure how low, they used to be about 1 GHz 25 years ago. But that could be where the problem is. - Original Message - From: Travis Johnson [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Thursday, July 24, 2008 10:12 PM Subject: Re: [WISPA] Direct TV interference from 802.11b client?

I think it does as far as the frequencies go. They have added a little frequency convertor box to the receive end to allow the receiver to select which block of IF frequencies it wants.

Re: [WISPA] Direct TV interference from 802.11b client?
Thanks everyone for the input. I'll get the customer to unplug the PoE cable to the client to see if its the power supply or something out my cat5. Reduced the client transmit power, and the connect rate of the client to 1M. we'll see what happens ...

They have added a little frequency colnvertor box to the receive end to allow the receiver to select which block of IF frequencies it wants. Two inputs allows four blocks of frequencies plus LNB switching would allow up to 8 different LNBs to be used with 2 coax' cables. - Original Message - From: Mike Hammett [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Friday, July 25, 2008 9:04 AM Subject: Re: [WISPA] Direct TV interference from 802.11b client?

Directv IF frequencies. Lower IF 950-1450 MHZ Upper IF 1650-2150 MHz So, we are not in the middle of either of those bands. The IF signal should be stronger than any spur an SM or SU could produce. - Original Message - From: Larry A Weidig [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Friday, July 25, 2008 8:25 AM Subject: Re: [WISPA] Direct TV interference from 802.11b client? We have seen this probably a couple of times ourselves. For us in every instance it was the power supply causing the interference. Easy enough to test, unplug the radio but leave the power adapter in the outlet connected to nothing. If still interference you can try swapping the power supply or move one of the two to a different circuit if possible. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jim Patient Sent: Friday, July 25, 2008 9:03 AM To: WISPA General List Subject: Re: [WISPA] Direct TV interference from 802.11b client? Are you using the satellite ground block? Is your ethernet cable running up with there cable? If so is it shielded? We have a number of installs literally on the same mast because they didn't want a second mast. We've never had an issue. We run our own ground from the radio to a ground rod and try to keep the cable away from the dish cable. Matt wrote: I had a customer call.

The customer has been installed for a couple years, but she swears that her 'pixelated' satellite reception on channels 3,5 and 9 are due to my system. The satellite folks replaced the dish, and head, and finally blamed my equipment mount a couple feet to the side of their dish. This customer claims that when pixelation occurs, she can unplug our equipment and the problems 'disappears'. Lets see, 2.4Ghz and what, 6 or 11G for the dish tv. don't see where on the RF front there is a remote possibility of interference. The coax goes around the house, our cat5 goes thru the crawlspace. Anyone ever have these kinds of issues? The customer expects me to re-install equipment on the other side of the house for free? Any suggestions? Can you lock the ethernet on a different rate and see if it makes a difference? Matt WISPA Wants You!

Re: [WISPA] Direct TV interference from 802.11b client?
Hi, We have had to deal with this several times over the years. If you can go to their house, see the bad picture, unplug their equipment and it goes away, then it's your problem. Just re-mount the radio farther away and keep the customer happy. Travis Microserv rabbtux rabbtux wrote: I had a customer call.

Re: [WISPA] Direct TV interference from 802.11b client?
I've seen that happen. Move your gear at least 6' from the dish and it should go away. I never mount closer than 6, preferably 10, feet from them anymore. Crappy receivers I think. Poor oob filtering. marlon - Original Message - From: rabbtux rabbtux [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Thursday, July 24, 2008 9:07 PM Subject: [WISPA] Direct TV interference from 802.11b client?
