best wire for outside wifi antenna?

------------------------------------------------------
coax or some outdoor grade cat5?

=============================================================== From: "kitepilot@kitepilot.com" ------------------------------------------------------ Oh boy... The explanation of this goes into the realm of radio frequency, which I am not expert of, so I hope someone else explains. The length of the cable has an impact on the quality of your link and has to be coax. The connectors depend on the manufacturer and you have to buy the expensive cables ready made, because the tools to crimp them are obscenely expansive. Or at least that's my experience... There is not a 'one size fits all' rule, but in general, the shorter the link, the longer that you can get away with the cable. And by 'sorter' and 'longer' I mean miles in between.

=============================================================== From: Bret McHone ------------------------------------------------------ I can't remember the math to save my life on the cabling, but as a general rule of t humb for ever connector you lose 1db of gain and it depends on the cable &length as to how much loss you experience. A few feet is no big deal, but if you are trying to run it any long distance then you will experience lots of loss. Actually, a quick google search found this cable attenuation chart based on length &frequency. Hope it helps. http://www.net-comber.com/cable-loss.html -Bret

=============================================================== From: Aaron Welch ------------------------------------------------------ When dealing with EM anything, a shorter "power" or transmit leg the better. The signal side or Ethernet in your case would be preferred. -AW

=============================================================== From: Rod-Lists ------------------------------------------------------ I get ET's remarks. I'm just wondering if y'all use some form of outdoor cat 5 or coax. Basically I want set up a dish or yagi to run a wire into a house to provide network. It will be pointed to a outdoor hotspot I'm setting up. ----- Original Message -----

=============================================================== From: Dave Brockman ------------------------------------------------------ -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Basically you want the cable from the antennae (coax, usually with the mini-BNC connectors) to the device to be as short as possible. I think you've picked up on that part. From that point, if your CAT5 is exposed to sunlight or moisture, unless you want to re-run it every couple of years, I highly suggest you acquire some exterior grade CAT5 w/ the black cable-snot in it. The exterior jacketing should also last longer in the elements than your ordinary spool of CAT5.

=============================================================== From: DaWorm ------------------------------------------------------ Antennas usually don't use CAT-anything multiconductor wire. Usually they use RG-something or LMR-something coax. For instance, for short wifi and cell antennas at work we use RG-174. For longer runs a low loss cable such as RG-400 or LMR-400 might be better if it is outdoor rated.

=============================================================== From: "kitepilot@kitepilot.com" ------------------------------------------------------ I have never seen an antenna wired with CAT-5 (or *ANY* CAT, for that matter) Is it even possible? ET DaWorm writes:

=============================================================== From: James Nylen ------------------------------------------------------ No. Coax cable doesn't radiate or absorb RF signals (as much) because the outer conductor acts as a shield. You need coax cable - otherwise the cable will act as part of the antenna, you'll get signal losses, interference, etc.

=============================================================== From: "Chris St. Pierre" ------------------------------------------------------ I bought my external antenna and amplifier setup from http://www.wilsoncellular.us. They were super helpful. Pricing seems about average compared with other online stores. At any rate, I'd recommend giving them a call, particularly if you need more than just the cable. The kit I got came with two 50' lengths of this stuff: http://www.wilsoncellular.us.shop/coax-cable-extensions/rg6. Seems to work fine, but unless you have very long runs of cable indeed, the cable wouldn't seem to be the most important piece of the system.

=============================================================== From: DaWorm ------------------------------------------------------ We use the Wilson cell signal boosters here. Good product. Jeff.

=============================================================== From: Dave Brockman ------------------------------------------------------ -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Twinax is quite common in the 10GB arena. Not Coax, but closer to Coax than [S|U]TP. Oh yeah, all those Comcast Internet users have Coax coming into their "gateway" device.

=============================================================== From: Rod-Lists ------------------------------------------------------ Yea I used to use phone wire as antenna once. Was able to pick up WABC in New York. CoaX from the dish to network. Tho I've not seen coax connection on network devices since the the 90's. ----- James Nylen wrote:

=============================================================== From: Stephen Kraus ------------------------------------------------------ Depends on if your radio is full duplex or not. If it isn't then you are more than likely using a single conductor shielded cable (co-ax). Most antennas utilize some form of coax anyways, unless the antenna is electrically steered or amplified.

=============================================================== From: Dave Brockman ------------------------------------------------------ -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've never (knowingly) used Twinax with an antennae, but I have seen Twinax 10GB jumpers (think switch to switch or switch to very close server). That and the Comcast reference for Rod, who hasn't seen Coax used in networking equipment since the 90's. Just wanted him to know it's alive and in use today, at every Comcast Internet Subscriber.
