Build an antenna for 40 and 80
With the help of the K7MEM site I learned that the dipole would be about 12 meter long
High-Q Coil Construction Techniques
n the past I used loading coils to improve the efficiency of a short dipole on 80m. The results, however, were disappointing. The main reason seemed to be the low Q factor of the coils
