Comet Original CAA-500 Mark II Standing Wave Analyzer 1.8-500MHz SWR & Impedance Simultaneously

My concern was being able to see the display in bright sun light. No problem and having the analog meter is a great help. Highly recommend.

ive several of the cheapees, this beats them all. As the old saying goes, you get what you pay for.

Easy to use. I think I read the manual first, but there was really no need. Its 95% intuitive for a ham whos experienced with HF. Id give it 5 stars, but Im dinging it 1 star for: 1. not including a case of any kind (got a nice hard-sided one for $25, see below) 2. the fact it should have a rechargeable LiPo battery included 3. that it doesnt have a USB port for exporting data to a computer for sharing with the world 4. that the 300-500 Mhz range is routed to an N style connector. I understand theyre less lossy at UHF, but practically how many of us use them? At least include an N to SO-239 adapter (which I ended up buying) This is probably the top of the line manual analyzer out there. If youre the sort of ham who thinks he knows better than a computer, this ones for you. You create the graphs either by auto sweeping a range or manually doing so. If you want to record the readings, youll have to do something like what I do: snap a photo of the display with my phone. Not elegant, but it works. Im sure there the Mark III will be out next year with a USB port. After using MFJ units, this is a definite step-up. It seems like a pro-grade item. I found the perfect hard case on Amazon. Only $25 and made in USA. Search for Seahorse 230 Medium Tactical Case with Foam, Black. It has room for the Comet, manual, and several adapters.

I needed to tweak three VHF/UHF antennas (LPDA beam, dis-cone & 50 MHz loop). This device makes it very simple to sweep the antennas. The dis-cone covered 50-500+ MHz and the Comet made it a snap to check it out. Recommended.

Did not come with batteries, and the charging wire needs some supply voltage. The should have at least included a proper charger. Otherwise, so far it seems to work well. I can test antennas to see if we have a problem there or somewhere else.

Well worth the money. It came damaged in shipping and return and replacement was easy/Peazy. Thanks Amazon

Very well designed and built! Price is fair and the Comet is packed with features that will serve you well. for the price you cant go wrong.

seemed well made , good value .

Its great for testing to see if that old length of coax is still good, and it makes tuning antennas easy.

I have used this device on many HF, VHF and UHF antennas and it has been very helpful. Based on this I should give it 5-stars. However, I gave it 4-stars as for the price I should be able to save the information to a computer. I know that other devices offer this but the advantage of this CAA-500 MK-II is that it spans from 1.8 MHz all the way to 500 MHz. Most of the others require you to either have multiple devices, or much higher priced single units to cover this entire range. Some of the others that cover a similar frequency range do not have graphic displays. I am a firm believer in visual feedback and a graph is much more informative than just measurements. Granted, the numbers are needed for engineering work but the graph is much more useful when you are adjusting and tweaking antennas. Likes: - The meter w/dual needles (easy and simple) - The multi function color LCD screen - The ease of use Possible Improvements: - Adding the ability to save the information so it can be displayed on a computer so the data can be further analyzed and stored - Replace the dual meter with an equivalent digital display. The needles are more fragile and they can cause some occasional issues if the screen gets excess static. Especially in dry environments. You need to wait till the charge dissipates from the meters plastic face plate.
