1.5 is perfectly fine needs no adjustment.Lately the max 2000 antennas have SUCKED. A local put up a brand new one and can't get his swr lower than a 1.5.
12" for another $50. It should have been called the "Max Sodimizer"The new ones are made for 10M. You have to use the "Max Optimizer" version or if you already have a MAX2000, you will need to purchase the 12" section for ~$50 to get it to tune properly on 11M.
I been putting 1500w into mine all day and 2200 peakI got mine just before they made the Max Optimizer version, so I extended the tip with a 12" piece of stainless soldered to the conductor. It's been great for 2+ years now.
Does anyone know what the true SSB power handling is for this antenna? Looking at doing a big station upgrade this winter, kinda hate to lose the multi band ability of the IMAX, but if it won't handle 2K+ I'll need to include an antenna in the upgrade.
