Don't have experience with the Maco
But have the Imax 2000 up with factory made radials at 40 feet above ground, and added some wire radials for 12 and 15 meters, allowing me to work vertically polarised from 19 to 30 mHz.
For the H.F i normally run an Fritzel FD-4 OCF antenna, with added coil and 30 feet of wire so that it will be resonant on 160 meters too.
This set up will allow me to run the 1 kW into the atenna of choice on the high bands, or the FD-4 from 160 up.
In the 9 years the Imax is up, never had an problem with it, near the coast of Holland where we have lots of force 8 to 11 storms.
Worked the world with it on 10 in the last solar cycle, just 10 to 100 watts was enough then.
Since then i bought and restored to new an SB-1000 from Heathkit, wich will work from 160 through to 10 meters after an modification, wich is allowed here as Ham.
Running 1 kW into the Imax regularly, it doesn't budge.
73.
