I have a squalo for 2/70 dual band at 40 feet above the ground.
Just under the Diamond x 510N which was rebuild from new with teflon coax cable to handle the 200 watts digimode and SSB, the squalo can do 800 watts the X510N standard 50 watts digital through the small capacitors i replaced with teflon coax cable as capacitors so the x510N now can handle 400 watts in FM if need be.
Qou can use 2 squalo's get about 8 dbD gain in total, no need for a rotator then.
Since i live in pancake flat country the squalo does fine, as does the X510N, i get out quite well on 2 meter with 200 watts 100+ miles SSB, digital 4 to 600 miles with a bit tropo.
And that just with not even quite good tropo.
6 meters i use the OCF antenna 7 wavelengths long gets out fine 1500 miles with some tropo, waiting for summer to do some more.
Good luck with the squalo if conditions pop up you will do fine.
