Topband: Antenna analysers in close proximity to BC station

Tom: is there data that nail down the horizontal wire to vertical wire ratio?  I see in that write up by wa1on mention of 2.25:1 h to v but...is that some rule that can't be violated or.../

For instance, assuming a vertical section height of 10' I could run a longer horizontal section but don't know if that gains me anything.

Thoughts??  Jim R. K9JWV

In other words, instead of driving 4' ground rods in at both ends I run a wire between the bottom of the terminating resistor and the matching balun.....I'm going to try the shorter version first - 10 feet up and 21 feet across so the full loop will be 62' of wire in that rectangular shape.
