Antenna for Marantz 10B


I recently installed a Marantz 10B into my system. It has an antenna "block" with a ground screw and two other screws net to the ground that are labeled for 300ohms. I have a 75 ohm cable coming in from the outside antenna or a 75 ohm cable from Charter. I have hooked up the Charter cable to the ground and one of the 300 ohm screws and it works but is it the best way? I live in an area with few FM options so the best approach will have to be good enough. Sure is fun to see the 10B sitting in the system. The tubes have all been checked with a few marginal that I will have replaced soon. Who serves as "the oracle" for this "holy grail" of tuners? Probably worth having it gone through by an expert so I can listen to the few available stations with confidence. Thanks...

I have had good reception with a C. Crane dipole connected to a Radio Shack transformer.
Crooner,
Thank you for all the valuable info. I tested the tubes with a tube tester I bought on 'gon a while back for my other tube stuff. When I install the balum I will note which tubes were marginal since I will need to order some soon. Again, thank you one and all.

Onemug is right recommended a simple folded dipole. Works wonders in strong reception areas where there is not a whole lot of multipath.

The original Audio magazine reviewer back in 1965 went one step further and glued the dipole to a wooden cross piece that could be rotated to reduce multipath. Excellent idea.

Marantz developed a couple of antennas for the Model 10B but unfortunately were never released.
