Excellent Time Owned: 0 to 3 months.
I just recently aquired one of these units as a "toss in" as part of an equipment trade.

As a long time Amateur, I am familiar with Heathkit, having built and owned many of their transcievers. However, I've never before even looked at their tuners.

I've only owned two tuners previous to this one, a Dentron (traded away many years ago, due to lack of experience and appreciation for quality), and an MFJ969.

The latter I purchased primarily for the roller inductor. The MFJ969 works, and the SWR meter is nice. However, I was quite dissappointed in the quality of the construction and hardware in general.

The first night of owning the SA-2040, I spent some time cleaning the case, which clearly had seen years of use.

Upon opening the cover to check inside, I was immediately pleased with the opportunity of owning this unit. The construction and quality of the capacitors and the roller inductor puts the MFJ to shame.

I expected a kit, especially a tuner, to be a functional but rough build. This unit was anything but that. The coupler shafts, counter gears, knobs etc.. were perfectly aligned. The tuning of all the shafts smooth and easy.

In a nutshell, the internal components and quality of design puts many currently available products to shame. It makes one wonder how we as a community (amateur radio) ever started buying into the relative "crap" that is available today.

Sure, this unit is big (14"W x 14"D x 6"H), has no built in watt/SWR meter, no dummy load and/or coaxial switch.

What is has, is excellent components and a solid design proven by the obvious years this unit has on it.

I've since used the SA-2040 with a variety of wire and other antennas and am quite pleased with the performance to date.

I wish I had come across this deal years ago before buying the MFJ696.

I don't plan on doing any modifications to the unit, save for perhaps touching up the paint one day. I kind of appreciate as is.

If you can get your hands on one of these, ot is worth it just for the hardware alone!

Solid tuner Time Owned: more than 12 months.
I have had this tuner for over 1 year, I must say it is build like a tank, and well designed for a T type network, The only draw back is it is simple, no meters, and only one antenna can be connected to it at a time. and no bypass switch, or antenna selector switch.But components are supior to most tuners out there in todays market. It is really easy and tunes nicely. I bought it for use with ladder line and it works very well for that. I needed a tuner with the old ceramic post. My other tuner Ten Tec 238B has plastic post for ladder line which melted when used with ladder line. The only way to solve this is to use ceramic post they handle the heat better for the large miss-match 80m dipole ladder line for all bands use. The SA 2040 was the answer. I only regret not have gottten a SA 2060. The ten tec is a good tuner It one Major Major asset it the L network design which I think is best matching network because only one match possible no circulating currents exist in L networks as in T matching networks. BUT thank god IT's NOT MFJ. I had one once but it lasted a few months and went up in smoke. I will never buy an MFJ again, A real waste of money. I like the Heathkit SA 2040.If you can find one they are really built to last and work very well. They really take a beating and really perform. Never a problem and it performs with ease.

Solid beast, but lacks convenience Time Owned: more than 12 months.
I got my SA-2040 several years ago at an SK sale. The price was "right" because it had been the victim of some never-completed mods. In the end, that was not all bad...

I know that purists and collectors abhore "unauthorized" modifications to vintage or classic gear. Well, this tuner had been owned by someone who cared more about convenience than collector value. How do I know? Well, there was en extra hole drilled in the lower front panel, between the inductor tune knob and the antenna cap knob, at just the right location for a heavy duty ceramic RF switch. Also, there were two extra roughly 5/8" diameter holes hacked (not properly drilled or punched) into the back panel. I interpreted these major blemishes to be attempts to add an antenna selector switch and the capability to connect to multiple rigs and/or antennas, and maybe a dummy load.

I'll spare the details, but I'll sum this up by saying that my SA-2040 now sports a front panel selector knob that switches one main line (from a transceiver or transmitter/receiver combo) to either a dummy load, Antenna 1 straight thru (no tuner), Antenna 1 with tuner, or Antenna 2 with tuner. I have an external 500 watt 50 ohm load connected, as well as an 80/40 inverted-V at Antenna 1 and a 120 foot wire at antenna 2. (Note: I use an external balun on the random wire antenna, with about 60 feet of RG-213 between the tuner and the balun.) I used all of the hacker holes, made only 1 new one (using a proper 5/8 punch to mount another SO-239), and did all of the internal wiring with either #12 wire or RG-213, as appropriate.

Summary: if you encounter an SA-2040 that has been hacked, consider the possibilities, especially if you can get it cheaply. This is a very well-built tuner, with one exception: the coupling to the gears which drive the turns counter seems to like slipping, despite repeated tightening and alignment. If I don't turn the inductor knob too quickly, it works OK most of the time. The balun appears to be quite hefty, and I might remove it and use it remotely for a planned 80m flat top. (I have no desire to bring open wire feeders directly into the shack. They are an excellent means to invite lightning directly to your operating bench or desk.)

What a deal - solid performing wide range tuner and potential to become even more useful, especially if someone else committed "unforgivable" sins to the cabinet!

Tunes the storm windows ... & more Time Owned: 3 to 6 months.
I've been a longtime owner of MFJ antenna tuners, but bought my SA-2040 on eBay when the price was right. While it isn't as fancy as its big brother, the SA-2060 (no SWR/PWR metering), it's one heck of a tuner. While matching the storm window is nice, the real difference between this tuner and other, inferior tuners is its efficiency. It seems to put more fire to the wire (a center-fed Zepp in my case). Compare the SA-2040 to some of the roller inductor tuners on the market, and you'll find there's a reason the SA-2040 and the SA-2060 sell so high on eBay -- they're built with quality components that work. If you can find one of these tuners under $175, consider it a bargain. You won't regret your purchase, and I suspect you'll get your money back out of it if you ever decide to sell it.

Great buy for 80-10 Time Owned: 6 to 12 months.
No fancy meters or 160M, but this thing is a tank! Extremely heavy duty components and a real buy for those who can find one. This thing will handle the limit all day long- try that wih your MJF and you'll be smokin! The parts alone are worth the typical $125+/- used price. I've used it with loops,zepps and L's. Couldn't find anything it wouldn't tune to 1:1. It's big- approx 14"W,6"H and 14"D, but not nearly as big as the Johnson for those of us with limited rig space.

Heavy Metal Monster Tuner Time Owned: unknown months.
Great tuner with only one problem, Only for 80 to 10 meter antennas. I loved mine but sold it when I found a Heathkit Antenna Tuner 2060A. This is basicly an improved model 2040 with 160 meters coverage and installed Power/SWR meters and antenna selection switches. Oh, regreated selling the 2040, it shure would be handy to have a second solid tuner for use on more antennas!

Boy, I was glad I had this old baby around! Time Owned: unknown months.
I moved some time ago and had my station in storage. I decided to get back on the air and went out and bought a Van Gorden G5RV JR. This was a cheap way to start operating again. I put the Antenna up and tired to match it up with my old MFJ-901. What a joke.I could not get the SWR down below 2:1 except on 40 meters. I was rather angry, but remembered my old Heathkit tuner. This baby has been laying around for a long time. Infact, I had not used it after I put up a beam at my old QTH. I went to the closet and got it out dust and all. I decided to open it up to make sure that the caps and inductor were dust free. I had'nt seen the insides of this baby for at least ten years. Wow, shes built like a tank! I hooked the old girl up, and I can now tune 1:1 any where. this baby is solid and could handle a KW with ease. I would rate this tuner higher, but it does not have all the bells and whistles like more modern tuners eg. meters, switches and such.
