FWIW (For What It's Worth)

I currently Use a set of profesional wireless units (one is an "AP" access point), the other is a "CPE" Client Premise Equipment (Client of the AP)

The connection is over 10 miles and the units with the right antennas will do 25+ miles.

If anyone is intrested, I would consider selling the extra units I have, with 50% of the sale going to the message board as a donation.

I have a total of 4 Ap's (Base) and 12 CPE's (Remote) all S/W and installation instructions, as well as I would be willing to "consult" free of charge for the install.

More than one CPE can talk to the base at once, so a small sharing network could be configured for people that live close to each other.


Price is open to offers, (again 50% would be a board donation),  units where over 1000 each new, 7 years ago.

OK, for what it's worth......

I remember a circuit that used a cap as the voltage snubber, in a LED readout, (instead of a resistor), the thing that the circuit designer said about the cap. is that it would NOT heat the same way as a resistor as a snubber, the process detailed something about the 60 cycles would take the cap "X" time to charge, so one could use the charge time through the resistance of the LED readout (assuming the portion of current the dispaly used as "Y" time constant, therefore X and Y can be used as a calculation of currnet requirement vs. charge time @ 60hz.) SO, what came out of it, was effectively a non-heating voltage devider circuit for quite a high amperage load.

Where I'm going with all of this is :

The Cap "sees" current as inrush/charge time, since it then discharges during the 0 cross of the AC cycle, ad restarts again in the opposite cycle, it is effectively a heat "null", BUT voltage reducer.

It still takes current to run the circuit (Cap portion I'm speaking) so the thing here is that this is NOT an inductive load, rather a resistive.

Someone said in a previous post that you could charge a cap but needed a circuit to keep it's charge.... NOT correct, we use to throw charged cap's at each other some 30 years ago in electronics class (with the leads bet over the sides so one would make the connection with their hand..... "SNAP" your fingers would go numb for about a minute or so....)
