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

Easy to use and well built.

It works fine below 300 mhz. The UHF side does give an accurate SWR reading. But the OHMS are always off. I fought with an antenna for over an hour, only to find out it was the meter itself. We hooked it up to a 50 OHM dummy load. It tested out at 1:1 SWR at 50 OHMS on two GOOD analyzers. The Comet read just below 25 OHMS across the entire 70 cm ham radio band. Apparently Comet doesnt have quality control!

seemed well made , good value .

Exactly what I needed!

Thankyou

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.

Dead simple to use. Quality construction. Get the case, this is not bargain basement equipment.

Great product. I analyzed an OCF wire that is designed to operate on all bands from 80 through 6 meters, and I can see exactly where resonance occurs and both the resistive and reactive components of impedance. The only negative is the screw heads that protrude on the back side of the box. This could be corrected easily and to me suggests an attitude of indifference to the concerns of customers.

I feel like somebody now! This is one awesome piece of equipment. It makes my well worn MFJ look like a crude piece of junk! Plus it will do uhf that I couldn’t do with the MFJ. Making and experimenting with home made antennas is really fun and now even more so.

Ive been wanting/needing an analizer for a long time now, been borrowing friends MFJ products and just never wanted to buy one of those. When I found the Comet CAA-500 and read about it, I was excited to give it a try. After having it for months now and allowing my friends to use it and compare to the MFJ products, it stacks up pretty well. In fact my friends are all wanting the Comet product now and appreciate its superior quality. I bought a small aluminum case from Harbor Freight to store/transport it in and it travels well. I love its capabilities and overall quality. Recommended product.
