Hi,
Yes you are very correct. The entire system apparently is working condition
so why not just leave it alone. That is ok.

But it is 16 years in the air and very green, coils are green. When looking
at the photos online the new ones while exactly the same design are
beautiful copper with a clear protective wrap around those coils. Mine
doesn't have that wrap and those coils are very green. The coils are smaller
diameter wire, looking like the transformer wire with that sholack on it but
then there are soldered connections back to the larger diameter bare copper
green wire running to the insulators.

I would have to make another core if I were to wind the same new copper wire
right from the center feed point to the ends of each leg. That would be
basically the only difference other than instead of bare copper wire (new
stuff) I have a big coil of solid copper wire with a jacket, I think it is
16ga. I was hoping to simply replace the exisiting bare green copper wire
and the green coils with new copper wire with the jacket.

So do you think the changing of the coil wire diameter but keeping the same
number of wraps is the way to go? Or because the new copper wire has the
jacket, this will change the number of wraps if I measure the length of the
old coil wire.

Lot of hardware in good shape on this old antenna, I just want to change all
the copper.

Thanks for the advice,

Hi
I got myself an old Alpha Delta DX CC now, it is old, very green. coils
look green also.

I want to rewind those coils or even rewire the entire thing.

This is the 82ft no trap 80 through 10 dipole. Also includes 12, 17 and
30.

Any advice from the group? I see the coils are using a much thinner
wire, new ones look nice and copper, this one is very green.

What size wire can those coils be? Can I just continue the copper length
for the 80m leg and instead of separate copper winding just use the same
copper and wind it around that winding core?

With the coil is the critical factor its length or number of coils?

Any advice from the group is greatly appreciated

82' No Trap 80 thru 10 Dipole.And it is great ALL bands. This includes
12, 17, and 30.


There are a lot of variables here. Most of which I do not understand. I
have enough experience to know that the number of turns in the coils is
most important and the diameter of the coil is important. If you use the
larger wire for the coils it will likely take a large coil form. You can
certainly use the same wire for the whole antenna. I am just thinking that
if they used thinner wire for the coils, you will not be able to get
enough turns on the form to get the same inductance.

If I were in your place, I would use some insulated stranded #14 house
wire for the whole thing. I would also buy some pvc pipe to allow the same
number of coil turns (and same diameter). If it worked fine before you
started this project, copying it wire length for wire length and turn for
turn would be my plan.
