Re: [TCML] Counterpoise Dimensions/ Moderator Suggestion



Great! Thanks for the replies guys, it always sounds so obvious coming from you... Shouldn't be too much more questioning before I get it up and running and I get some videos posted up here.

Hey, there's an idea moderators, why not host our "amatuer" coiling videos in a designated section on pupman somewhere? Then again, hosting a non profitable server storing gigs upon gigs of videos may be costly... Just a thought.

Thank you all for your unconditional helpfulness to us here!

In this case it perhaps makes sense to position a breakout point so that the
streamers shoot out over the longer dimension of the sheet.

2x8 feet sounds pretty reasonable to me for a NST powered coil.

Hi Brandon,



It will "work", just not as well. Think of a tuning capacitor, where the "effective size" is changed by moving one plate out from alignment under the other. Think of the topload as one plate and the counterpoise as the other- making it long and skinny takes some of its area out of the most intense
part of the field.

ALso, the whole point of a counterpoise, typically, is to give a "preferred route" for the RF current flowing in the secondary. Since the field from the topload is more or less symmetrical, having the counterpoise more or
less symmetrical helps.

But, hey, it's a guideline, try it and see.
