Hi, I have just put up a Moonraker SQBM 500 2mtr 70cms aerial.
It seems a bit deaf to me, any one else found this or could mine be faulty?
Many thanks for any help.

What is the SWR like?
What grade of coax are you using?
Deaf compared to what?

That's probably because that model resonates on 9mtr & 23cm:-)

this is the spec I have found


SQBM 500 DUAL BANDER 2 METRE 70 cms CO-LINEAR 2 mts 6.8dBd 70cms
9.2dBd

If you suspect it is faulty, get it replaced and ask wbat it does resonate on.
You say deaf, compared to what ?.

At the moment I only want to use it with my Icom IC-PCR 1000 for 2mtr 70cms
receive.
As I do not have a transceiver yet I do not have a SWR meter, but will be
getting a transceiver some time in the future.
The Moonraker SQBM 500 seems deaf compared to my discone aerial.
The coax is thick low loss, I do not know the grade number. It was given to
me so I could try out the aerial.
On cutting the coax to fit the plug I found the braid was tarnished but
cleaned up on scraping it.
Could this make the aerial deaf? I intend to buy some new Siva R-H100 coax
from Nevada when I get the transceiver.
Many thanks for your help.
Baz

I suspect that the coax you are using is goosed (Sounds like second hand
UR67). If the braid is tarnished it looks like it has had water in it.
The siva 100 is ok I got a drum from Nevada last year and find it ok.
once again I would suspect the coax first off, try a short length of
rg58 or similar 50 ohm coax that is known to be new.
ps if you are getting coax from Nevada I would suggest that you invest in
the correct type of coax plug at the same time, I have found that the outer
shell on some "normal" pl259 plugs are little bit too big for h100. Nevada
stock these anyway.
In truth I would prefer to use "N" type connectors if possible but if
the ant comes with a so239 fitted you will not be able to change that unless
it is on a short co-ax tail like mine was.
One idea would be to recruit a local licenced amateur to come around to
your qth and fire some rf up the thing.

What does a CB aerial (sorry antenna) manufacturer
know about making aerials that work ?

it's NOT deaf......it's a Moonraker.....they are crap, always have
been......CBers realised this years ago, so they turned to AR to con yet
more suckers.....dump it, get a Sirio.....

RIGHT! A CB aerial is a very sorry antenna indeed!

A CB vertical is only 1 s-point below a 3 element yagi and costs less.

I Brought one before XMAS, X510n and it was ok till sections parted after one
month and let water in causing the VSWR to go sky high. This has killed the PA
brick and left me out of pocket and as such I would not perchase a thing from
them again. As to date they have only returned the cost of antenna, this has
not included my P&P and damages to radio!

What a bunch of complete morons. An aerial is an antenna, is best constructed of highly conductive material as radiating elements, the brand of the aerial is immaterial (except to brand-junkies, morons), an aerial will seem deaf when used to receive frequencies to which it is out of resonance. All aerial manufacturers will try to rip you off, you should all learn a little bit of fact rather than Bullshyte before actually posting a comment. Nuff said

Or short version "it's a Moonraker"
Aerial made to look pretty by CB manufacturer for good buddies

One S point is 6dB, about the gain to be expected from a 3 element Yagi when compared to a 1/2 wave dipole.

What about the Beverage antenna? That's non-resonant.
