Dear Pratap,
Another line of thought, starting with Walt's comments: How big is
your dish? Getting a bigger dish could increase the low end boost
enough to make a difference. The current Telinga dish is about 22
inches in diameter, if memory serves, and can be had for under $100.
If your old dish is significantly smaller (I don't know if Telinga
used to make smaller ones), then this might help a lot. I am sure
even bigger dishes can be had from other sources.
Cheers,
Gernot Huber
