I have a home built Yagi antenna, and for the 5 elements on it I used 14 guage copper wire (stranded) (I am not using high wattage)Do I need to strip the insulation from the copper wire for the antenna to function? (as you might have guessed, it is not).
I probably wouldn't strip the insulationCopper oxidises over timeThe skin effect tends to concentrate the current in the outer layers of the conductors and copper oxide does conduct, but not very well! You haven't said what frequency band you're working on, but a few questions come to mind: How precise have you been with the lengths of each element and the spacing between them? You need to be really accurate to get good results at VHF/UHFAre you using a balun to connect the cable to the driven element? A coax cable implies an unbalanced feed, which doesn't match all that well to a balanced dipoleYou tend to get r.fcurrent flowing down the outer screen of the coaxA simple quarter wave sleeve balun is better than nothingAre you using a folded dipole for the driven element? A simple half wave dipole on its own is not a bad match to 50 ohms, but the interaction with the passive elements of a yagi tends to bring the impedance down quite a bit to the point where it's not a good matchA folded element offers a much better matchI take it that you have put a SWR meter on the thing to check for matching? The results can be misleadingHave you allowed for the velocity factor of the wires when calculating the required lengths?
That is not normalI'm sorryMy little girl had peeling skin for about 3 weeksAfter a good coconut oil massage it went awayYour baby sounds like something is really irritating his skin! Hope it's easily remedied!
Probably just dry skin is causing tthe peeling try using baby lotion twice a day that should helpAs for the bubblss id be very concerned about thisDoes not sound normal to me at allIve never even heard of this happeningm definateky have ur baby checked out by a pediatrition/doctor asapI personally would take baby to the emergHope bubbs is better soon
We cannot help you but ill tell you that is not normal.
