Feeder BOX(Edit)
- This box contains of transformer 450 Ohm to 50 or 75 Ohm and protections


- Part list
| PTC_F | PTC 5mm | piece 1 | PTC 100mA |
| GL | Neon lamp | piece 1 | neon lamp 100V |
| Tr | Transformer | piece 1 | BN-73-6802 |

TRANSFORMERS winding - very important thing!(Edit)
- for 50 ohm coax feed line : 2 turns on primar (coax) and 6 turns on secondar side (loop)
- for 75 ohm coax feed line : 2 turns on primar (coax) and 5 turns on secondar side (loop)
- Transformer should have 5 + 1 turns. So you wind 5 turns and 1more as a tap.


Common mode current choke(Edit)
- Common mode current choke construction
- Wind 4 turns on one side than cross to another side of cores and wind rest turns.



Terminator BOX(Edit)
- This box contains of Load resistors for the antenna and protections

- Part list
| PTC_F | PTC 5mm | piece 1 | PTC 100mA |
| GL | Neon lamp | piece 1 | neon lamp 100V |
| R1 | Resistor 2W | piece 1 | Ohm 750 |
| R2 | Resistor 2W | piece 1 | Ohm 330 |
| R3 | Resistor 2W | piece 1 | Ohm 470 |
| R4 | Resistor 2W | piece 1 | Ohm 560 |
