I've never seen one for a DB224, though I have seen them for a DB408 (4-bay
UHF) with 9 degrees of downtilt.
A DB224 has a pretty fat 16 degree beamwidth in the elevation pattern. You
sure you really need downtilt? If your problem is dead spots extremely

Hi All,
If you have a tracking generator and can check the notch skirts to see if that
will give enough isolation between freqs on the notch cans,
You could use the 2 or 3 notch cans on the TX side to notch the RX freq, then
use the 2 or so pass cans on the RX side.
Hope this helps and good

Hello again,
The decision making circuit probably draws less than 10 to
20 milli amps above about 8 volts. Less than 8 volts pretty
much nothing. The core decision making circuit is pretty much a
very ingenious single zener diode controlling a bipolar
transistor circuit.

controller, for which I paid Tessco about $150. It operates at 24 VDC and
uses two Siemens 90 watt panels and two Concorde 250 Ah AGM SLA batteries.
The repeater is a Motorola MTR2000 running at 80 watts output. More

The 100 to 200ma to hold the coil in on some of the older LVDs can be
more than the entire load at some sites.
I run several solar powered digipeater sites where the standby current
is 50ma.
Last summer I ran across the Samlex LVD's that are all solid state, and
the load is only 4ma.
