As promised, here is a brief review of the Justice AM Antenna.
I got it a couple of weeks ago (for $50.00 -- they had an "orphan"-- their term for returned "like new" merchandise). It arrived in perfect condition. It is very simple to put together. In fact, they made it so that it can't be put together wrong -- the plugs are all different. The kit consists of a pad with the adjustment knobs, a short coax (they offer a 20' as an accessory), a "universal" ferrite attachment, an A/C adapter, and the actual antenna assembly (which is about the length of a telephone handset, but only about 1/2 inch thick). The antenna unit is weatherproof and has screws included for external mounting. The tuning pad has an outer bezel with a mark on it, which serves as the coarse adjustment, and an inner knob that serves as fine-tuning. Numbers corresponding to AM frequencies are on the dialpad. Using it is simple. To listen to WOAI (1200AM - San Antonio -- I'm near New Orleans) you first tune your receiver to 1200. Then, watch your signal strength indicator (I have a CC Radio Plus) for a spike as you tune the dialpad to 1200. When you see a spike, move to the fine adjustment to maximize it. That said, I believe it would be fairly difficult to use this antenna to its full advantage without a signal strength indicator. On typical nighttime stations, you will hear a slight volume increase as you tweak in your station, but the biggest difference is that you'll find that it no longer fades out. My power bar for WOAI/1200 would normally read 1/4 to 1/3 -- with the Justice antenna properly tuned, it pegs out full strength. This ratio seems to be universal, as I tried stations from 600 to 1610, and the boost in signal is always about + 2/3. If you already get a station at 1/3, it's going to peg out. I do not have the antenna module in an optimum spot, either (but I'll get into that later). There are two ways to connect the antenna: The first is an adapter plug that plugs into a standard RCA phone jack and gives you two wires to screw onto your external antenna terminals. I found this was not as sensitive as -- The second method: There is a little ferrite adapter (about the size of the cap of a sharpie marker) that is flattened on one side and has an RCA jack on the end. Plug the RCA lead from the dialpad into that, and put the adapter on your existing radio (near the internal ferrite antenna -- you'll be able to tell optimum position by watching the signal strength meter). My first foray into custom mods was attaching a little Scotch tape under the ferrite adapter so that it doesn't fall off my radio. Worked perfectly until my daughter's cat....well, I digress. The performance of this thing is simply amazing. I have definitely not given this antenna any advantage, because the actual antenna unit is under my bed, on the floor. (I know -- that's heresy in the rec.radio.shortwave newsgroup. Please -- no flames -- I'll move it this weekend.) My radio is on my bedside nightstand, and my bedroom is on the bottom floor of a 2-story house and has other rooms on 3 sides (I do have windows facing west). I was able to do away with the turntable I used to use with my radio. This antenna lets you actually have the radio face you (instead of the distant station). The antenna is omnidirectional. If you have a couple of stations on the same frequency, all of them will come in stronger. It is an antenna, not a sync mechanism -- your radio will have to sort it out. That said, I have been able to tweak some signals very well using the dialpad. For me, this thing is perfect. It's easy to use, and only has the footprint of a credit-card on my nightstand next to my CC Radio+. The only improvement I could think of for this antenna would be luminescent numbers on the dialpad. It's not terribly difficult tuning in the dark once you've done it for a while (due to the signal strength meter on my radio), but it would be handy. I hope this has been helpful. -- Stinger Picayune, MS |

- Very helpful;
- May get one ! Thanks Dan In article , "Stinger" writes: Subject: Justice AM Antenna (from C.

You have my interested peaked, sounds like the antenna works really well.
Scanned thru the C.Crane Co. orphan's section, but no Justice AM Antenna. Is it listed frequently as an orphan or do I need to just keep looking? |

All:
- This device uses a 9 volt battery; I assume it has an amp in it; - else why the need for 9 volts ?? - How's it work without the battery ??

![]() "Bill Beam" wrote in message ... I also purchased the $50 Justice Antenna and have had great success with it. Really pulling in AM stations and increasing listenability (word??). Very happy on my purchase. And always fun to have a new knob to turn. I'd recommend it highly although at $100 and shipping it may be a touch expensive. That's my concern--the ol' cost/benefit issue. I have no doubt it's a nice antenna, but how much better is it than my 19.95 Rat Shack loop, which I'm pretty pleased with? I've had the same c/b issue with the CC Radio, which is promoted as the last word in AM radios, but is apparently helped more than a little by adding the $50-100 Justice antenna. Will this set up be noticeably better than the AM section of my 7600G with Rat Shack loop (total $180, including SW & FM)? Perhaps, but for some (like me) relative performance for the dollar is an issue as well. |

Thank you, Gray. I'm looking forward to hearing the results of your
"subjective test." Judging from the literature that came with the antenna, they suggest best place for it is on or near the sill of that window. I've got to fish a wire through the wall for the longwire I'm hooking to my ATS-909, and I'm seriously considering fabricating an extension lead for the Justice antenna module as long as I'm at it, and mounting it high in my attic. Vicksburg is a beautiful town -- I hope you're on one of those huge hills! -- Stinger "Gray Shockley" wrote in message .com...

![]() "Moonman" wrote in message t... Snip Also, is there any kind of effect as your hand approaches the antenna to rotate it? I'd guess that "hand capacitance" effect would be unremovable. -- Moonman I've moved the antenna unit around, and don't notice much difference in signal either from "hand capacitance" or from being pointed in different directions. Moving it closer to a window, etc. helps, though. -- Stinger |
