Re: [WISPA] Lightning arrestors
You have to check the specs. The possible problems are high VSWR. Rather than transiting through the device the radio waves bounce back from the device. This could damage your transmitter, will reduce your transmitted power, and increase receive loss (reduced receive signal strength). It's also possible for the device to maintain a low VSWR (still present a 50 ohm impedance at 5.8GHz) but be very lossy (reduced transmit power, reduced receive signal strength). I don't believe the lightning protection benefits are any different between units for different bands. The difference is how it passes the RF signals you're trying to pass through it (loss and VSWR).

[WISPA] Lightning arrestors
What happens if you use a 2.4 lightning arrestor on a 5.8 radio? Will it cause degraded signal or incorrect lightning protection. Regards Michael Baird WISPA Wants You!

Re: [WISPA] Lightning arrestors
Hello, Yes if it is not rated for up to 5.8ghz. You should be able to find specs on the lightning arrestor. -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Michael Baird Sent: Saturday, November 28, 2009 10:01 PM To: WISPA General List Subject: [WISPA] Lightning arrestors What happens if you use a 2.4 lightning arrestor on a 5.8 radio?

Re: [WISPA] Lightning arrestors
I second that. Most ARE rated for up to 5.8 but don't seem to list it unless you ask. Last time I purchased them I found the ones listed for 5.8 only were much more $$ than the 2.4. Turned out the 2.4's I was buying were indeed rated to 5.8, I just had to ask to find out. Makes sense, why make 2 when you can do the same with just one product.

Re: [WISPA] Lightning arrestors
They are rflinx quarterwave rated from 2.1-2.7, they were used instead of polyphasers on a couple of new backhauls we deployed. I'm seeing unusual noise floors on both of them which I know are incorrect due to the readings from previous 5.8 gear that was replaced. I'm just wondering if this would be a symptom, what does the frequency range actually mean on those I suspect it would make my noise floors go out of whack like that. They aren't in use and I will replace them before going into production, I'm just curious. Regards Michael Baird I second that. Most ARE rated for up to 5.8 but don't seem to list it unless you ask.

Re: [WISPA] Lightning arrestors
We carry quite a few different ones. Most popular are the PolyPhasers, go thru 7GHz. http://www.quicklinkwireless.com/items.asp?Cc=LIGHTNINGPROTiTpStatus=0; Tp=Bc= Regards, Chuck Hogg Shelby Broadband 502-722-9292 ch...@shelbybb.com http://www.shelbybb.com -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Robert West Sent: Sunday, November 29, 2009 12:08 AM To: nsto...@wisperisp.com; 'WISPA General List' Subject: Re: [WISPA] Lightning arrestors I second that.
