I'm going to be building a homebrew satellite antenna over the weekend.
I am confident that I will have little trouble doing so, in the construction of the actual antenna. I've built some different antennas in the past.
Here's my problem though.
In building the duplexer/diplexer, the parts list I have, is requesting certain ceramic capacitors. 4.7 picofarad, and 10 picofarad. Seeing nothing like that at my local shack shop, I came home, and used a capacitor conversion chart, to see which microfarad capacitors I could use in their place. Same local shack shop carries NOTHING with that many zeros in it (they do carry the 10 picofarad cap. Not ceramic. Electrolytic.)
Does anyone have any suggestions? Cap substitutes? Can I use a bigger cap? smaller cap? (Do the caps have to be 4.7 microfarad, & 10 microfarad?) I live in a town of maybe 10,000 people. The closest anything besides this shack is over 2 hours away in Las Vegas.
Ham radio is pretty dead out here, so I figured if I can work the birds, it will keep my interest peaked, and my radios will not end up dusty, in a box.
Any suggestions will help the gears of progress to turn faster.
Thank you.
