Nice Analyzer  Time owned: 0 to 3 months
Well, I've only had my analyzer for a week but must admit, I've put it through it's paces. I have been in the process of changing out several of my antennas from 160 meters through 432 MHz. One nice thing about this analyzer, it covers 222 MHz!

I haven't had any trouble with the threads on the coax connectors like some other reviewers. I love the smooth action on the cross needle meters, one for impedance and the other for SWR.

It is accurate as I've compared it to my MFJ-259B, my MFJ-269 and my YouKits FG-01. Accuracy, they all agree on the ranges that each covers. My initial reason for buying the CAA-500 was to have an analyzer that covered 222 MHz which the others didn't cover.

I think the CAA-500 is easy to use and easy to read with the big meters and display. Us older coots who are having more and more sight issues appreciate that. ;=)

The only drawback I see is that it suggests that you use 1.5 volt Alkaline batteries only and not any rechargeable batteries. The rechargeable batteries only are rated to 1.2 volts as compared to 1.5 volts in alkaline batteries. They claim the lower voltage create issues and recommend only alkaline batteries.

All in all, I think this analyzer is great and I look forward to using it a lot in the future.

I'm satisfied so far!  Time owned: 0 to 3 months
I bought a CAA-500 two weeks ago, along with a Diamond dummy load for the initial testing, and an Amphenol SO-239-to-male "N" connector adaptor for use when required....I've used my CAA-500 only VHF/UHF at this point, but all seems assured that based on a previous review, I'm always very very careful when turning the screw as I open the battery trap-door....I'll write further CAA-500 reviews as necessary :-) with my previous MFJ-259B, I keep my CAA-500 in a nice perfectly- fitting black-handled and zippered "cosmetic case" that I picked up a few years ago at a discount store....

Very Good Choice  Time owned: 3 to 6 months
I purchased the Comet CAA-500 Analyzer and it seems to work very well! I have checked my hf through uhf antennas and it seems to have an accurate readaing compared to a transmitter and vswr meter in line. I have even found problems with my antenna switch that I have had for a while and will not buy that brand again! I have ordered a new Alpha Delta to replace it. As the old saying is true you get what you pay for!

A question....  Time owned: 0 to 3 months
Does anyone know if the initial SO-239 connector irregularity with the CAA-500 has been corrected? Are the CAA-500s now available from the major US retail vendors now equipped with the SO-239 we expect here in the USA? I'm not sure just how to describe the connector, but it's the style that's been sold for decades on HF here in the USA. It's the style we all grew up with :-)

Dead-On for Me...  Time owned: 6 to 12 months
I've owned this Antenna Analyzer for over 6 months and have run the gauntlet with antennas galore. It's behaved famously.

However, if the batteries (6 AA) get weak, your readings may be off. Always stay on top of your batteries in this unit. When they get too low, you'll get bad readings - plus the unit ships with cheap batteries. What battery powered device doesn't?

Has a Problem  Time owned: 0 to 3 months
Liked the equipment and is very useful, but screw to battery compartment was impossible to remove before stripping the head. Thought about returning it for another but felt the 2nd one could pose the same problem.

not Accurate !  Time owned: 0 to 3 months
Rcvd CAA-500 yesterday, put it on the low band antennas 40,80, the MFJ-259-B had correct readings. when xmiting swr pwr meter were the same . the MFj-259-B checks with the HP-8753e network analyzer. using this Beautiful CAA-500 the readings were eronious..! It may be beautiful but not having correct readings is unfortinute and has to leave this shack! there are BC stn's with in 2-3 miles, but they do not bother the MFJ-259-B. It's not beautiful but reliable for tuning the antenna tuner with out a carrier and other testing. GL 73 Returned to AES yesterday BUMMER....!

Very good quality  Time owned: 3 to 6 months
Yes, there is a minor issue with the UHF connector, an adapter will work just fine.
I simply replaced the connector with an N and use adapters as needed.
Build quality is excellent!
I built up an internal battery pack and charger and replaced original tray and power switch that I mounted on top as the original can be easily depressed by accident.

Still working great  Time owned: 3 to 6 months
@ John VK2KC

In the time that I have owned mine - since May 2011 (Dayton hamvention), I have probably connected around 30 or 40 DIFFERENT PL-259 connectors on the unit. Some of the connectors were purchased in the USA, some in the UK, some here in South Africa (probably manufactured in China) and some came already attached to cable ex Japan. I can only recall one connector giving me trouble - but at the time, I thought it might have been the PL-259 connector shell that might have been damaged. All other connectors that I have used, have seated completely.
I don't dispute your claim, and clearly there is an issue if Comet have admitted a thread incompatibility, but I have not found the same problems with mine, when used with connectors that I have here.

I am still happy with my purchase, I think the quality compared to the MFJ units, is in a different class. For power, I use the rechargeable batteries that are sold through the Apple store. They are very high capacity, and I am still using the original ones I put in, in May. I am confident they could last a year before requiring a recharge, although it would probably be better to swop them out before then.

I like the very large size of the analogue meter, and in fact far prefer it, to MFJ's use of a combination of small meter and digital display of values. I would like to have had rubber "feet" on the back, to avoid scratches when laying it down. I will add my own. Apart from that, I cannot fault my unit.

John, ZS5J

Thread stuffup  Time owned: 0 to 3 months
More on the incompatible thread issue.

I have been in contact with Comet in Japan and they had admitted that the connector will NOT fit the US standard PL-259 connector. They HAVE used the 16mm x 1 mm pitch thread, they call it an International Thread! All PL-259's have a 5/8" x 26 threads per inch pitch.

Here is a copy of the email sent to me regarding the incompatibility of the threads on the lower frequency connector.

Hello Mr. John McLean,
Thank you very much for purchasing our CAA-500.
The CAA-500 first lot does not have international standard connector.
From the second lot, which will be released on NOVEMBER 2011, we change the CAA-500 connector so that PL-259 connector will screw onto the CAA-500 M-J connector completely.
Would you please so kind as to send your CAA-500 back to us?
I will send you the new one with international standard connector, then.
We deeply apologize for the inconvenience we have caused you.
We hope that you will continue to choose COMET products.

FAX : 81-(0)48-839-3136

So ALL CAA-500's sold in America WILL have the WRONG thread on the low frequency connector.
Contact your supplier, and I hope you get a better response that I received from the supplier I bought mine from in the USA.
DO not force your PL-259 on the connector, it will damage the thread and render your warranty null and void.

I have relented and spent $70 Aust to send the CAA-500 back to Comet in Japan, along with a sample of a PL-259 so they can check it on the replacement unit before they ship it back to me.

Her is the second email I received from them:

Hello Mr. McLean,
Thank you for your reply.
Our exchange policy is;
the customer covers the freight fee to COMET, then COMET will offer the new one and cover the freight fee to the customer.
Technically, this is not our mistake because we donít think itís wrong connector.
We usually do not make connector international standard, because we donít feel the need to do that and our distributors purchase our product with this understanding.
From second lot, we decided to make CAA-500 connector international, not because the connector is wrong, but because lots of oversea customers request international standard connector.
We usually exchange the CAA-500 because we think itís true that our product does not satisfy the customer anyway, even not by our mistake.

Please send your CAA-500 to;
Comet Co Ltd
4-18-2, Tsuji, Minami-Ku,
Saitama-shi, Saitama-pref,
332-0026, JAPAN
TEL : 81-(0)48-839-3131
Thank you for your understanding.
Mika Yagishita

An expensive lesson.
