is that adjusted for resonance of the 1/4wave line DB,

seems odd that adding the upper 1/4wave caused significant current to flow in the short at the top of the 1/4wave line when theres nothing flowing in the upper 1/4wave,


edit are the wires from source to antenna 7" each side lengthening the transmissionline off resonance ?


thanks


ps,

i meant the model with optimised 1/2wave mast since we know the astro does not like the mast ending up next to the hoop,
