Old look antena for wifi

[keegster17]

Guys my girlfriend has a old "Look" communications Antenna on her roof, with a RG6 old beige colored cable running down the side her house, right to the point of her local cable company box. I assume at one time this was used for digital cable, and internet? Is it possible to convert this and use it as a wifi antenna? I read something you can on another forum, but i am not sure. I have a DDwrt router, I was thinking I could extend the cable from outside and somehow attach. Maybe someone could let me know and I will ask more questions later if possible.

Can you post a photo of this so called "Old look" antenna?

It would be possible but the RG-6 coax has too high a signal loss for the TX side of the router, by the time the signal go to the antenna it would not do you any good.

Also the required adapters (RP SMA to F) would cut the signals down to nothing by the time it got to the antenna.

Most TX/RX coax for routers are 50 ohms impedance and are used for the transmit side of the router, you also need a very low signal loss coax or again it wont do much good.

Most of the WIFI local antennas used now days have the modem right at the antenna, I use one that has this type of setup, all that is inside the house is a power injector for the CAT6 cable going up to the antenna.

I also have a router (Amp wireless) with a 600 mW output feeding a yagi antenna using RG-214 coax pointing to a friends house 1 mile away, She has a USB WIFI device running at 1 watt sending info back to me, works good.

Ahhhhh now I see it.


And to the answer to the orignal question, it's NO.

Not without removing the feed horn (it has the TX modulator in it) and replacing it with a 2.5 GHz antenna (like the removable one at the back of some routers, or some other type) set at the focal point.

Range on that antenna is 2.5 to 2.7 GHz, but you don't have the TX driver for it.

The best way would be to use one of these hummers.

Mounted up on a mast, and one end hooked into a 2.5 GHz yagi antenna on an old TV antenna rotor, you can get stuff from miles around.

And here is a bit of a cheaper option, it uses a USB connection, you then hook it into the antenna of your choice. (directional or omni)

Terryl, so no pic required now correct? you know the antenna i am talking about? Wow $200 plus for the one mentioned, that's a bit much, but I don't mind your second option, what do you think of that one? what would be my range vs a Linkseys router with ddrwrt?

[Terryl]

You still can't use that antenna, not without modifying it, you have to put some other type of antenna at the focal point on that dish to get it to work right.

The last option I mentioned would be a better one as it would mount on that antenna or outside on it's own, in the attic, on a balcony or close to a window, you then just plug it into the USB port on your PC or laptop and set it up.

It's just like a USB WIFI adapter.

Terryl thanks...will this work much better than my ddwrt router?

[Terryl]

It all depends on what your are trying to do?

Terryl have you ever ordered anything from the company on your second link? Is there something the same local for my area, I am in Toronto, Ontario.
