RE: NEON- Neon and radio interference
Thank you for your explanation, Marcus.
Doesn't it mean that if there are no other aerials but sat dishes on my roof, there is nothing to worry about.
Even with solid states???
Then another question to all.
What things do you consider when choosing a transformer for a job? What transformers are appropriate in certain installations?
Maybe some statistics: what percentage of electronic converters vs. conventional transformers do you install in a year?
regards
dmitrij

Dear Dimitrij,
Don't know exactly - haven't done experiments up to now. The abt. 30kHz main
oscillation should not kill the TV converter, even at high electrical fields.
More affecting could be the corona discharge in my opinion, the Field effect
transistors used in those converters are VERY sensitive to static discharge.
When the converter is well shielded (i.e. complete metal case), this should not be
a big problem. Plastic cased units are suspect to me in any case.
If the antennas at the location you have to install the sign are for those
VERY VERY high frequencies as satellite dishes, you should not expect interference
in any case. Long- medium and short wave radio will be much more affected by
neon interference.
