Does anyone know what the relation between frequency and dielectric strength is? I'm mainly concerned with the dielectric strength of air in the High Frequency and Very High Frequency Ranges (3MHz - 300MHz). Thanks.

I'm not sure it helps, but I googled "paschen curve" +frequency, and got some reasonable hits. Here's an abstract for a paper that may apply:

Ooo, and this abstract mentions frequency effects in atmospheric pressure breakdowns:

This is for argon gas:

Standing waves could prove to be more of an issue
