DTV / NTSC
Stacked Antenna Systems
- Excellent Solution for Top Mounted Systems.
- Mechanically Bottom Feed Design.
- DTV Power: 20 Kw Avg. - 28 Kw. Peak.
- NTSC Power 70 Kw Avg. - 78 Kw Peak.
SWR's "Clarion FT" Series is a stacked antenna system for both DTV
and NTSC channels regardless of channel assignments. The only true omni-directional
antennas are top mounted, and this design will allow you to keep your present
top mount site rather than share with a less desirable panel-array. SWR's
"Clarion FT" antenna is unlike other stacked antenna systems, where the
feed for the top antenna is fed thru the aperture of the lower antenna,
and this can have a devastating effect on the pattern of the lower antenna.
Our design, however, would allow the feed to the top of the antenna to pass
throught the lower antenna, thereby eliminating any possibility of interference
between the two.
