Rick- I"m sorry I sounded so strident, but this subject has progressively
wandered astray. The subject started about a particular cage being hyped as
having 5db gain over a reference Dipole AS TESTED. A cage is not the
question; HIS cage is. (To me).
I agree that your results are interesting (I hope to apply the idea) but
people are introducing dBi, dBd , analysis (undefined) and the classic
"Ordinary NEC wont work with my special invention", which is the point of
his claim.
I may try to model it myself (next week) because I would still like to see
for myself. His product (without hype) looks like a fair buy.
