[Hybrid tellies]

Many moons ago when I was about 14 for a time we lived on an old MOD estate in Helston Cornwall.

I had an old HMV 1124 valved radio which I used as my main radio as well as for short wave listening. I used a 60' long wire aerial across the garden with a mains earth. Reception was ok but the noise levels especially across the Long, Medium and lower frequency HF bands could be rather high at times especially during the evenings when everyone was using their televisions.

Access to a separate earth became available and what a difference that made. The noise levels across the lower frequency bands dropped significantly and the performance of the long wire aerial seemed to improve especially across the higher frequency short wave bands.
