can i use my old cordless phones' tech to make an active wifi antenna?


i've been looking into wifi antennas such as the parabolic dish biquads.

those are passive devices, undriven, and then it occurred to me that i've got all sorts of old cordless phones in the 2.4 Ghz and 5 Ghz ranges.  is it possible to use the tech in those as oscillators/amps to boost wifi signals?  like maybe feed the biquad with their circuitry?

Sounds like a great ides, but something it bugging me about the concept.....mostly because I am not as closely associated with how wifi hooks into the computer, as compared to how a phone is......if the "phone out (into the computer)" would end up still being "analog" you may be in for some real work to get it working.

Do the old cordless phones have a better range than your existing wifi?

that's a good question.

insofar as i can tell, my Airlink 101 AR430W router with its stock dipole antenna only sees about 30 meters, but its manual doesn't really say and i'm not going to go and take my laptop and walk around to find out, tho i'm pretty sure the 19 dBm given for it isn't correct.

my latest cordless phone is a Uniden DXAI 5588-2 and i got reception for several blocks when i had occasion to walk around with it one year, waiting for an important phone call. but it's a 5.8Ghz, and i'm sure the cartload of 2.4 Ghz cordless phones i've got laying around in the backroom, with their stock dipoles, can't do much better.

why? what were you thinking? : )

The DXAI 5588-2 sounds good, it sounds better than things I've used.
I don't know how these things are built well enough, but it's an interesting idea.
Can you identify & isolate the transmitter/receiver in these phones?
