Title: Extending the wireless antenna of the wireless cams
Post by: ytuxedo002 on January 28, 2007, 09:31:35 PM
I read a little post a while back that said they had removed the antenna off the wireless cam, spliced in some 50 feet of telephone wire and placed the antenna next to the receiver.

Does anyone have any instructions on this or where i could find them.  I've been searching all day and can't find anything.

Thanks in advance.

I doubt telephone wire will work at all. A 2.4 Ghz transmission signal would be lost.
Maybe some miniature coax but this would kill the FCC type Acceptance, If it even works,

What about incorperating something like this http://www.alertelectrical.com/CCTV-Professional/Wireless-CCTV-Cameras/Wireless-CCTV-Transmitters-Receivers/24GHz-Video-+-Audio-Receiver-15-2400VR.asp

It's a 2.4ghz video/audio receiver.  Has anyone tried using something like this to increase their reception?

Actually X10 did carry something similar to that so it should work! this seems to have better range though the x10 version only added 100 ft!
I do like the Caution: tag as it is very true! ;)

You may need to check that the 4 channels on it match X10's 4.

Good point Brian!
ytuxedo002  a  quick note (e-mail) to  the manufacture would confirm this!
Ask if it is compatible with X10 wireless cams! ;)

Yea i'll try that...thanks. 

Do you know the frequencies of the 4 x10 channels??

I believe the Channel frequencies for X10 are:

X10 cameras and Video Senders use the following frequencies:

Channel A: 2.411 GHz
Channel B: 2.434 GHz
Channel C: 2.453 GHz
Channel D: 2.473 GHz

question? is it possible to extend the antenna using telephone wire or other types of wires? im kind of new for wires so thats why im asking dumb questions, but i guess no question is dumb unless you keep it to yourself thats why im asking. can some one please be clear on this situation thanks.

Telephone wire would be a poor choice. The cameras use a 2.4 Ghz frequency that plain phone wire would not pass well. Maybe some small coax rated for that frequency may work.
At my local discount store they had a wireless network antenna and I was toying with that idea.

This network antenna is in the 2.4 - 2.5 Ghz range - not sure if the other specs are compliant. Anyone know about dBi and ohms? It comes with just the right length cable that I'm looking for.

50 Ohm coaxial cable that this antenna comes with is what you need to have proper impedance matching... definitely not phone cable.

The gain of 7dBi means that in one particular direction, this antenna is better than a true isotropic antenna. Since this antenna is omni-directional and the law of physics states that energy cannot be created nor destroyed, then if it's better than ideal in one direction then it has to be less than ideal in other directions. So if you use it, you may have to play with the the positioning to get optimal transmission.

I haven't used this antenna at the transmitter end, but I have used it at the receiver. It works, but I think it ended up picking up all my neighbours phones, network & microwave signals... so as a receiver it wasn't as I hoped.  :D

I've added about 10 feet on 3 of my cameras antennas the signals are just great.
The main reason though was those 3 cameras were on the Ninja and obviously the antennas moved with it.
