Consider this...today you might be thinking of a 6sq ft antenna...next year
you might be thinking of a 15sq fto antenna...you can always go to a larger
antenna, you can't upgrade the base if you skimp on it the first time.
If you don't want to spend the money on concrete you can use pea gravel with
the proper base fixture. Then if yo move you can jack the base out of the
gravel fairly easily.
Good Luck,

> The tower specs are also available at this site. The HDBX 48

> maximum size antenna boom is stated to be 10 feet.
>
> The foundation for the base stubs is concrete measuring 5.75 feet x
> 5.75 feet x 4 feet deep = 4.9 cubic yards of concrete.
>
> If one plans to only use the HDBX 48 with antennas that do not exceed
