In-the-Attic : Terminated "Twisted" Folded Dipole (T2FD) - Think Twisted -not- Tilted !
Bob,
N9NEO {Bob} has the #43 Ferrite for building his own Baluns so a 4:1, 9:1 or 16:1 should not be a problem. 4:1 (2T-to-1T) = 24 Turn Primary Antenna Windings and 12 Turns Secondary Coax Cable Windings 9:1 (3T-to-1T) = 30 Turn Primary Antenna Windings and 10 Turns Secondary Coax Cable Windings 16:1 (4T-to-1T) = 32 Turn Primary Antenna Windings and 8 Turns Secondary Coax Cable Windings The other Part of the T2FD is the Terminating Resistor and an In-the-Attic T2FD Antenna may require some Adjustment {Play-With} the Terminating Resistor to get the Antenna to yeild the All-Band Coverage that is sought from the T2FD Antenna. more to think about - iane ~ RHF |
