t they could have done is buy some good
commercial mono band antennas for the repeaters. Would have only cost a couple
hundred extra, and the system would have worked ten times better. Oh well
can't make everyone understand common sense and logic.

Here is my dilemma. One of my current work radio sites is being decommissioned
and torn down. My new replacement site has some antenna restrictions and I'm
having trouble finding an antenna to fit the bill. The old site is 110 ft.
tall and I have a DB-264 antenna set for omni pattern at 6 dbd
Ah and guess what Motorola has changed that yet again on the new Quantro's.
Now the new Quantro's use the standard 100 watt internal PA throttled back to
drive just one single high power PA to get up to 350 watts. No more two
external PA's on the Quantro's.

ade please let me know. I could also use one of the RTL-5815
adapters for the SyntorX EEPROMs, but I don't need
one like I do the one for the MSF.

Does anyone know the formula for calculating the distance between two DB-252 corner reflectors that are connected by a phasing harness? I'm sure this is frequency dependent and I want to get the spacing correct. Thanks T.J. KC8LTS

What does the list think of the 411 vs. the 413? I'm using the 408 now but I'm looking to cover into a one particular direction over the other.

You could try this antenna. http://www.decibelproducts.com/productnotebookantenna2.asp?Param=ModelNumber&Model=DB314-A&freq=on We used this antenna at my work for our interoperability initiative. You won't like the price though as it was over $1000.
