Well we all deal with Tessco but when you deal with
the
large box house you get NO consumer service. And
no
tech support. Yes you could have ordered your 224
from
Tessco tuned for your transmit but you would have

This is also why you get different spacing on
the dipoles. It also depends what year in time
your harness was made. Over the years they
changed coax with new owners (of DB) and that
also
has a spacing change. Be careful. If you are
and do it right you will not have to buy a new
DB-224.

When I converted my 224 to VHF amateur band, the element length went
from 35 inches (150mhz unit) to 37 inches (144mhz). The spacing on
the elements was somewhat limited by the new harness length. Had to
work with it a good bit to get somewhat equal spacing on the pole.

Wrong.
The only way to get downtilt on a binary fed exposed dipole array is to
either build the phasing harness so the electrical length feeding each
element is slightly longer in pha

I just measured mine (not as cold in North Florida as for you guys,
but it was interesting to measure the deminsions on my two antennas:
Both Had top element center 26" from top of pipe (so that was OK.)
Both had 34.25 inch loops (top to bottom)(reasonable)
Both had 62" separations from center

has 35 inch loops on an 18 ft mast.
