Theory says 5/8 should be the winner, but of course it all depends on exact installation, position etc.

I want to know the exact dB gain of the exterminator or dominator. I intend buying one but will like to know if it will be suitable for commercial radio broadcasting.

It is exactly as written on our website under antenna specs, that's 5.15 dbi

The antennas are practically identical, exterminator has a better CNC machined head.
