The T2FD Terminated Tilted Folded Dipole Operating Notes and Design Data on the T2FD System From N. P. SPOONER ( G2NS ) ( from Short Wave Magazine ) While it is true that quite 75 % of a station's performance depends upon the aerial the ...
... T2FD and DX - Listener Antennas The famous T2FD caused enormous interest in shortwave circles when revived in the 1988 WRTH . Just 15 metres long , this low - noise antenna has no frequency " blank spots " , unlike dipoles , trap di ...
... T2FD . However I have no place for original T2FD , and I already have installed the 14- meters length of wire , that is why conversation to be applied only to the wire . Figure 2 shows schematic of the antenna . Resistor for 50- Ohm is ...
... T2FD питается по 75 омному коаксиальному кабелю через симметрирующий трансформатор 6:1 на кольцевом сердечнике. В эксперименте по сопоставлению T2FD и настроенного вибратора антенна всякий раз уступала ему 1–2 S ступени [70] ...
