Fritzel MFB-13 on rotator

I’m so happy with the results of the Fritzel MFB-13 that I decided to put it on a rotator so I can swing it around from the shack. I had an old Daiwa DR-7600 lying around with DC7011 controller so I spend the afternoon installing that. I also put up my MasPro WN59N 2m/70cm combi yagi (not connected yet) in case I want to do some USB on VHF/UHF in future.

I tried to model the MFB-13 in MMANA and calculated the loss. On 10m it’s about 0.1 dB (it’s a full size dipole with the ends folded back about 40cm, on 15m it’s about 0.3 dB (not sure if that’s correct), on 20m it’s about 3 dB (half of an S-point). I’m probably going to use it on 10m/15m mostly because I didn’t have an antenna yet for those bands. 20m works fine on my EFHW as well so I have a choice now.

Pretty cool set up right now don’t you think?
