Grunow 1291B antenna question
#1

Hi guy's and gal's.
Have a Grunow Teledial model 1291B That I am having issues with the proper antenna hookup.
This chassis has 2 antenna terminals.
One is for antenna and the other is labeled Doublet.
I assume the doublet is for shortwave?
I know I have to have about 40 ft of single wire attached to the antenna terminal to get rid of motor boating on certain stations.
With no antenna, motor boating.
With 20 ft of single wire, still have some motor boating.
With 50 ft of single wire, no motor boating.
Tried tweeking the alignment with no change.
Anyone out there have one of these models?
If so, what are you using for an antenna?
P.S. this radio is re-capped and working well other than the antenna issue.
