More learning curve here
Been looking up inductance and worked out by coiling me vertical antenna that 10% off the mark 1/4w 40m LOL yep random wire with idea of nearness to 1/4w . But looked at the coiling effect by using a cal that shows dia of the pipe am using length and how many coils. And it shows if pipe was smaller or more coils on me pipe the inductance increases in uH from what i can see.
Now question is if greater amount of uH ( think got that right) is introduced like it did when first did it by making me coils next to each other so they touch and found 40m would not tune in by any means But by spacing them out by at least 1cm apart its less inductance and can tune in 40m and 80m no problem right up to 10m…
Now idea of coiling some of the 11m wire (3m) i use is to loose some of it on way up but keep the over all length of the wire in a little smaller space.
Also by reducing length of me wire over all down to 10.2m and try tune into 7.1mhz better. how much increase would i get out and in. And yes the antenna does tune in at present on all bands i can use of HF down far as 80m. Be nice if i could make the antenna more better. better still would love one of those fancy gadgets. Or how big re these losses am prob encoring.
PS don’t forget one is not to high up doing the maths stuff
Some more experimenting required i thinks
