Sent the program to George, Bon & Hal. If anyone else wants a copy you can ask myself or them. Please do not post It in a file section on any groups, (I look in those), It's copyrighted. It's nothing fancy but does a fairly good job with some nice little utilities to boot. Old as dirt but hey I did'nt pay for it either. To the ones that get it, please let me know how you like it. I have another that's great for calculating transformers and other such good junk. Enjoy

Was on an older machine. Norton picks up a virus, ARRGH, so i will remove it and send it to ypu. You can share this amongst yourselves but I would appreciate if you DID NOT upload it to any files section of ANY group , it is copyrighted. Back to removing the NYB, wish me luck --- On Sat, 4/24/10, kevin valentino <kevinvalentino@ sbcglobal. net> wrote: From: kevin valentino <kevinvalentino@ sbcglobal. net> Subject: Re: [Repeater-Builder] Re: how far To: Repeater-Builder@ yahoogroups. com Date: Saturday, April 24, 2010, 9:00 PM OK there is a "cute" little program that actually comes fairly close to calculating effective radio range based on height, power, line loss(has a cable database), and frequency. Add the cavity losses in with the line loss. Calculate the portable at 6 feet, unity gain, using worst case terrain type scenario. I will send it to you. --- On Sat, 4/24/10, George <gueorg...@yahoo. com> wrote: From: George <gueorg...@yahoo. com> Subject: [Repeater-Builder] Re: how far To: Repeater-Builder@ yahoogroups. com Date: Saturday, April 24, 2010, 8:43 PM ok the antenna is from cell site 14dbm 4-element in a plastic housing, the amplifier is 600 watts capable linear mosfet 8element hybrid splitters and combiners... but the power supply is up to 65 ampers at 24 volts, driven by a "C" class 130 watt amplifier. the antenna is not on a commercial tower (no luck here). 20 feet above the house. the line is heliax andrew semi-rigid. the repeater is in the attic and the line is 30feet. the duplexer is celwave doesn't like more than 450 watts in. --- In Repeater-Builder@ yahoogroups. com, kevin valentino <kevinvalentino@ ...> wrote: > > Any approximation would depend on the repeater antenna height and the terrain > of the area. > I would hate to see the price tag on an 800MHZ 450W amplifier :-) > I do mean literally "approximation.
