I've tried it a couple of times and never had enough signal to make it work.
If you have a -70 signal at the first receive antenna then you're basically going to transmit at -70 or so (instead of + 1 or 3). Running the calcs it looks like a receive signal of -132 at 2 miles. Remember, at 2.4 gig you gain 6 db every time you halve your distance. So at 1 mile it would be -126, half mile would be -120 and 1/4th mile you'd still only see a receive signal of about -114. Near as I can tell this only works well if you have a LOT of power. marlon ----- Original Message ----- From: "Steve Barnes" <st...@pcswin.com> To: "WISPA General List" <wireless@wispa.org> Sent: Monday, June 07, 2010 1:43 PM Subject: Re: [WISPA] Repeater Ok I have never even thought about doing this. Does it actually work? This sounds WAY to simple. A 29Db Grid on a Grain Leg pointed at the AP that has a -68 signal plugged into a 24 DB Grid Pointed to the house 1/4 mile away. What kind of signal would you have on the back side at the house?

Wire a coax cable between the two dishes and you are done... no electronics to fail, no power to supply on a remote location.
