Default Antenna Pre-amps MFJ 1020C

Do a lot of travelling and like to cruise the SW bands etc. Anyone use or
have any comments on the MFJ-1020C indoor active antenna preamp?

Performance? Bands etc.?

Thanks

Default Antenna Pre-amps MFJ 1020C

Dear Mr. Green,

I own the original MFJ-1020 and the later MFJ-1020B. Both are adequate
- no more - when used indoors with the short whip antenna. If you are
able to attach 20 feet - any more and you'll overload it - of
insulated wire to the back via the RCA jack and can run that wire
outside, the performance will improve greatly. The trouble, of course,
when traveling, is that you have to open a window (not always possibly
in a hotel) to run the wire outside.

It might be worth a try, however, as it is not too expensive.
Personally, however, I would recommend trying a Sony AN-LP1 Active
Antenna for about the same price. Unfortunately that antenna is
available only from a Japanese eBay dealer called Buy From Japan. I do
understand, however, that he is extremely reliable and ships very
quickly. (I personally have never dealt with him.)

Best,

Joe

the r20 isn't going to be able to take much of an antenna w/out
overloading badly on hf. it simply wasn't designed for that sorta
thing. i've had my r20 overload before on the hf bands with only a
sangean an-60 reel-out wire

on the upside, you can back off the gain with the mfj unit.

much better off taking that money & putting it toward a Kaito/Degen
1103 for your hf listening, or spending more & getting an icf-sw7600GR
for hf.

Thanks RHF! Excuse the top posting, but your information is utterly
magnificent...kudos.

My thought on the MFJ 1020C active pre-amp is that such is self contained,
easy to pack, has the appropriate controls, comes with a vertical
telescoping mast 50+ inches and looks like it would be easy to setup and
use.

Wires are nice, but messy on luggage and sometimes airport security get
curious.

So the question is does the MFJ 1020C do the job.

SD GREEN,

Yes the MFJ-1020C could "Do The Job" as you have defined it.

You have an RF Gain Control and Attenuator built into the
Icom IC-R20 and a Gain Control built into the MFJ-1020C.

Active Antenna Signal Overload - Back-Off on them to reduce
and prevent any Signal Overload of the Radio.

Remember - That you have to Tune both the Radio and the
Active Antenna to the same Frequency to use them properly.

TIP - With a Scanning Wideband Radio you may find a Wideband
Active Antenna the better 'choice' versus an Active Antenna that
you will be Required to Re-Tune with each Frequency change.

Thanks RHF. I looked at the options you suggested, but I rather fancy using
the various adjustments to fine tune the signal. The IC-20 does have
satisfactory controls to tailor the signal. For my purpose, the IC-20
performs quite adequately and much, much better than either my Eton 10 /100
or my Grundig 400. SSB is especially outstanding.

It was a toss up between the IC-20 or the AOR 8300. In the end, battery life
was the deciding factor.

How do you find the R20 other than the bandwidth? The specs look pretty
good for sideband. The price has been lowered a bit also. I'd get a
Yupiteru 9000, but the lack of a computer interface prevents that.

The R20 seems a better deal than the 8200.

====================

The ICOM R-20 is a pretty impressive communications reciever in my view. I
also run a ICOM 706 transciever and a old solid state Heathkit SB303 unit ,
and without question the IC R20 is more sensitive with better selectivity,
certainly on SSB signals. However like all communications recievers, the
unit does require an antenna. The provided telescoping is basically useless.
The battery life is a real plus with experience in the 18 to 20 hour range
(not scanning). The ANL and NB seem to work ok. For LW/MW the am side could
be a little bit more narrow, and like others have said ICOM should have
included that feature. VHF/UHF and beyond work really well. The R-20 seems
to be solidly constructed. Some features could have been implemented
differently like the TS control. The integrated IC Recorder is of interest
and also works well.

I also have the computer usb interface and software, where one can easily
input / change station data / scan edges / modify any one of the 1200+
memories.

I have four antennas, (1) 260 foot long wire (2) 23 foot VHF dual band
vertical (3) 12 foot VHF -lo 6m (4) 163 foot dipole from which I can select.
The R-20 reacts well without overloading.

For a small package, works well. I assume the AOR handheld wide band would
work just as well.

Wow, that is impressive. Compared to the performance of your R20,
mine would appear to have been defective out of the box. In
considering this radio, I was well aware of the prevailing view that
such wideband receivers often involve compromises, and I was expecting
just that. Therefore, given the performance that the unit provided, I
was neither disappointed, nor overly bowled over. It was about what I
expected: nothing more; nothing less. There's a lot to be said for
the R20: nice, small package; amazingly broad coverage; battery life
is quite decent, indeed; 10 Hz tuning resolution (although my unit can
show some variation; say, minus 90 Hz or thereabout); recorder is a
nifty feature, as is the standby mode it permits, allowing for
unattended listening; and I could go on.

However, for VHF/UHF scanning, it does not offer the trunking features
or APCO-25 decoding that some of the upper end handheld scanners
offer. Scan rate is also a bit slow compared with the dedicated
scanners, or so I've been told.

This receiver really wasn't designed for optimal HF reception, and I
realized that going in. Yes, as Mr. Green said, it's pretty deaf off
the whip, at least on the HF bands. I'm mostly in the Washington DC
metro area, so there's always plenty going on in the VHF/UHF bands,
particularly in Prince George's County... For SWBC listening, the
exceedingly wide bandwidth filter leaves much to be desired. True,
there's SSB tuning, and that somewhat compensates for the AM bandwidth
inadequacy on HF. Overall, however, for SWBC listening, I must say
that I get better performance out of a Sangean ATS-606. While I
purchased this unit to use as a handheld (i.e. as a portable unit),
I've hooked it up to external HF antennas of varying sorts (e.g. 100
foot wire; AOR WL-500 active antenna; etc), and to some degree or
another I have tended to encounter overload issues. Use of the RF
gain is essential, needless to say. I've experienced overload when
utilizing the R20 with a Sangean AN-60 reel-out wire antenna & Miracle
Ducker inline antenna tuner: nothing horrendous, but it was
noticeable. Ultimately, however, I use the R20 mostly as a handheld
and generally just using a whip. For me, the R20's HF side is simply a
nice extra for occasional tuning to major SW broadcasters. At home, I
tend to go with the Drakes (R8B/R7/SW8) or any one of a variety of
portables, most of which outperform my R20 for HF reception.

mike/MII: Yes, as a package the R20 is in many ways a better overall
deal than the AOR AR8200 Mk III; however, if you're into SWBC, then
you should consider the fact that the AOR does include that 3 kHz
narrow AM filter...something that prove a much desired feature, if you
were seeking a wideband handheld for which you intended to do a bit of
SWBC listening on more crowded bands, particularly if listening to a
weaker station in the presence of stronger ones...the little guys can
get drowned out in AM mode on the R20; SSB mode can in some instances
salvage the signal, but not always. The AOR costs a bit more,
however; and there are a lot of extras that are offered as options; if
desired, these can really drive the AOR price up. That said, David
Rickets seems to be really impressed with the performance of his AOR
8200 and maintains that it gives him pretty solid HF reception just
off the whip. For your reference, there are a wealth of user
assessments of the R20 available online; the receiver has tended to
get favorable reviews, by and large:

http://www.strongsignals.net/access/...rocess=display
www.monitoringtimes.com/html/mtscan1104.pdf
http://www.grove-ent.com/ICR20REVIEW.htm

On the whole, the R20 is a nice little receiver. An interesting
attempt at an all-in-one package. ICOM has certainly packed a lot
into this little unit. It's really great that Mr. Green has found
such satisfaction in his unit. Going on his results, I'm led to
wonder if there are some significant sample-to-sample variations in
R20 performance. I guess Yahoo groups would be the place to
investigate this sort of thing further...

Thank you both for the insights. It appears that, as in everything else
in life, there are trade offs and compromises. The AOR is a pretty good
set, but I wasn't too impressed with the need to buy cards and then have
a limited space to use them.

We'll see how the funds are next month before deciding on a purchase of
an R-20. Now, I'm busy trying to decipher the inner workings of a Yaesu
