Good morning all,
We sell the Maggiore and when you team it
up with an Arcom 210 controller you can't
beat the audio. They work very well from
what I have seen. We never get them back
for repair. This is bad for us as we have a
repair business. Maggiore has a nice web
site you can go visit
We have used the ARR PD receiver power
dividers (PD-2 and PD-4) they work well
for us on projects. The price is not bad at
all.

I forgot you can do the following for 8

Hello All,
I do not know about some of the bands that are
posted. I do know that with Kenwood, Kenwood
Systems and Maggiore you get a two year wan tee.
With Motorola, Midland and Johnsonyou get a 1

We do not carry any thing else. I am not in radio
sales but I do know ifI buy a new car
Hey Kevin,
I am not saying it is bad to buy older stuff.
Just if you do not have the test equipment
or know all the ins and outs you mite be

I am real sure your converted stuff works
just fine. I see lots of folks come in and out
of our shop each
No they do not build 220 but Maggiore does.
BTW we have built systems that work across
whole states. But you are right I guess and
I do not sell used stuff like you do so as I

Hi Bob and the Group,
I have seen Russ's set up on his SUV
and the DB-404 is not a large antenna
at all. His mount folds backwards. It
is made for the Tar heel low band mobile
antenna.
I would not use a mag mount for any thing.
What would you gain by having a repeater
using a mobile antenna
1st off that was not a put down!
I will not blow my on horn but
I can say if it works for you then
use it. BUT! It is not how antenna
physics work. Just think how much
better a system will work when we do
not try to change the laws and rules
of antenna physics?

Hello All,
And good Monday morning!
Sorry for my delay but I do not work every week
end.
The reason for the 8 DBd on the flag pole support is as most
of us know they compress
the pattern the higher the gain and flag pole supports are not
that high. If you go to high in gain your coverage

Hello All,
We install many of the flag pole antenna supports as
well as the pine tree supports here at work. You will be fine
with
your 440 Ham band antenna. But watch your gain.
In DBd do not go any higher then 8 DBd. Plus no down
tilt.
Have fun!

We just checked the FCC list and it is not there we call the

Hello All,
This is all good and right on the money!
But reminder that every 3 db cuts your
signal in half. I would not use the 9913

Less loss and you will not get the static

The Kenwood TKR-840 is a fine repeater. But I have noted
that
most of the Hams seem to buy the Kenwood TKR-850 and

Good morning all,
If you need to use an RG 8
type of coax and it is below
500 MHz the Belden RG-214/U
will work OK. Make darn sure
that it has the /U on the end.
I would still try to use the Andrews
super flex where you can (or even
supper flex if it is in the evening)
A bit less loss.
Hello All,
You will want to use a hard-line coax cable.
I would say 1/2" will server you well at 50'.
Yes 7/8" would be better but the price
of the hard-line and the price of the connectors
would be much higher.
One thing you did not mention was jumpers.
This is also very important on a

Hello All,
The DB-224(e) should be 1.1:1 or very close to
it.
The impedance should be some where between
48 and 55 ohm. I know 52 ohms would be nice

a few DB-224's in the two meter range after
work today and the above is what we got using

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.
If
There are questions that need to be answered!
Are you using the tower for a reflector?
The rule of thumb is to be at least 1 wave
length off the face of the tower at the transmit
frequency some times more. We need to know what
you want for a pattern? Omni get your DB-455
away from the tower.
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
had
to wait for it.
Good luck!

Hello All,
Do not count on this info being right.
The top needs to be right from the
top of the mast support pipe to the
1st dipole and then center to center
on each after. If the support pipe is
not long enough get a longer one. They
come in different lengths one for 222
is shorter then
Part of the different's is between the harness.
Different'sin factors in the coax used.
That is why we have to watch out here at
work when repairing DB-224's. Be careful.
Over the years and with change of ownership
DB has made changes along the way.
Dean Westbrook, EE,PE.
This is 100% correct right of the DB chart.
You will be just fine if you set your DB-224
up this way!

The local club in NJ that did
