Hi. I'm planning to install two RAMI 529 antennas.
I studied a post from gmcpilot where he explains how to calculate speed loss from antenna surface.
I now managed to deduce such antenna produces approx. 2,4 lbs. @ 187 mph., which is approx. 1,22 engine horse power loss.
I can't make the final step to calculate mph loss.
Formula was 1/3^[(HP-HP loss)/HP]*speed.
So, if in my RV9A with 160 HP I can reach 187 mph., I should say:
1/3^(158,78/160)*187
It is not clear to me what "1/3^" means
Don't think I'm crazy. My calculations give me more than 0,25 mph. drop per antenna! That's why I'd like to solve this issue.
Thanks.
