!!TRANSFORMERS winding - very important thing!
** for 50 ohm coax feed line : 2 turns on primar (coax) and 5 turns on secondar side (loop)
** for 75 ohm coax feed line : 2 turns on primar (coax) and 4 turns on secondar side (loop)
- Transformer should have 4 + 1 turns. So you wind 4 turns and 1 more as a tap.
