We put up a the classic ON4UN 580 ft Beverage Ant..... with the 9-1
matching torroid exactly a shown in his Low Band DXing handbook,....we
checked the transformer input with the MFJ259 and a 500 ohm resistor on
the secondary....it was flat SWR for 1 to 10 mhz... we fed it with 75
ohm RG59, abt 100 ft.....We paralleled some resistors to get about 500
ohms at about 4 wts.. How critical is selection of the terminating
resistor?? Can it be anything from 400 to 800 ohms ?? Or does have to be
5% or less.... in my case using the 75 ohm coax it would come out to be
675 ohms.....Is it just nit picking???? or does this REALLY matter????
Does it NOTICABLY improve receiving performance when the resistor is
matched exactly??
Or can it only ....as they say....."Be measured with sensitive
instruments??
tnx Whitey K1VV
