developed and patented a method by which virtually any conventional type of
antenna can be made into a multiband design with a
single feed line.
The MacTenna system provides
multi-band coverage while eliminating interaction between separate antennas for
each band. The MacTenna system also reduces the
visual clutter of multiple antennas with separate feed lines.
The MacTenna system is very
cost effective when compared to multiple individual antennas with multiple
supports, insulators, feed lines connectors, and a coaxial switch to select
The MacTenna system also
eliminates the need for a separate antenna tuner which is required with some
other types of multi-band antennas. MacTenna
multiband antennas have low SWRs and wide bandwidths on all bands. Other types
of multi-band antennas have high SWRs and narrow bandwidths and usually require
an antenna tuner.
do not have strange radiation patterns with multiple deep notches like other
multi-band antennas. MacTenna antennas radiation
patterns are like normal single band antenna types.
