Works for me  Time owned: 6 to 12 months
I have only had my Alpha Delta 4 position antenna switch for a few months now, 6 months I guess. I have found no issues what so ever with this switch, seems to work FB for my needs. Coincidentally, this Alpha Delta switch replaces an MFJ 4 position switch I had had in place for over 8 years. If I can get 8 years out of the Alpha Delta, then I'll consider it a good switch. Until then, we wait and see, use it normally.

Great item!  Time owned: more than 12 months
Man, I couldn't disagree more with the previous review. Alpha Delta makes fabulous switches, as they include very stout switching contacts, lightning arresting plugs, and the paths to the individual N or SO-239 sockets are internally isolated by the integral die casting. The switching is solid and positive. This is a great product line....I can't imagine what would have prompted the previous review of them.

Not a great switch  Time owned: more than 12 months
A new switch had a dead position. Since it had sat on my shelf for more than 2 years, it was out of warranty so I opened it up. Very surprised at the contacts, they are relying on a piece of ribbon wire to make 'edge' contact. The problem with the bad position was poor alignment with the contact. Easily bent to make contact. Poor design and poor quality control. Would not buy another one.

Jury is in  Time owned: 0 to 3 months
Got my switch back from AD and it is better but the switching still feels a bit cheap. It works but the shaft still wobbles a bit. I guess it's just the design. It would be nice if they could incorporate a traditional rotary switch into their design. I wouldn't buy another unless I could try it out first.

Perfect for 15 years  Time owned: more than 12 months
I have used a variety of Alpha Delta DELTA in both our commercial and my amateur station for many, many years without a problem. I was talking to Jim at Alpha Delta several weeks ago to order several more switches and we were talking about customer "problems". He said 90% of repair returns are due to the customer over tightening the set screw over the D-4 gas tube. That will distort the thru-lines in the switch and cause malfunctions. He said their instruction sheets and WEB site say NOT to tighten the set screw from the factory setting. But, apparently people seem to tighten down the set screw any way.

The switches I use have never been fiddled with and work perfectly.

Original's-great / newer-need help  Time owned: more than 12 months
Currently have a total of 14 ( 4 and 2 position ) switch's in use at a contest station and at home. The old "original" AD switches work flawlessly. The newer one's are another story. I have had to repair several. Have had the plug inside melt because of a poor contact between the metal strips thus causing heat. Replaced the plug using teflon (not sure what it is they use) and adjusted the metal strips for correct alingment and contact and they are back working and no heat issue. Have to check and tighten the set screw on handel of every newer model. We use them because of a varity of operators and easy to switch to antenna desired. I would rate the original (older) AD switch at 5 and the current production 3. Also when I called and finally got to speak with someone who said they would send the part needed right out; well, its almost 2 years and I'm still waiting for the part.(rate that as 0)( in use for 10 years) For a solid contact at switching with no issue out of the box, use a Bird.

Jury is out  Time owned: 0 to 3 months
I'm giving this switch a 3 for the time being. When it arrived the shaft was wobbly and the switching was not smooth. I emailed Jim Burns at AD and he said to send the switch to him and they would "make it right". It's been two weeks so I'm expecting that I should receive it soon.

What puzzles me is why they just didn't incorporate a rotary switch into the design. It is well built but the switching mechanism seems to be a bit suspect. After reading the reviews it looks like its a hit or miss experience with their switches. For $80 it should flat out perform with no issues.

Intermittent contact  Time owned: 0 to 3 months
I just purchased this switch. After I connected the rf cables to it I found position "1" was intermittent. When I switched to that position I had a 50-50 chance of making a connection. I didn't check the other positions. I removed the switch from use because I can't rely on it.

Fine so far  Time owned: 0 to 3 months
I have read about the knob coming loose, mine was loose right out of the box. Not a problem though if that is all that's wrong. Only about a minute to fix. Working fine so far.
I mounted this one on a angle to a removable shelf. Seems like a solid product, we will see how it holds up.

Solid  Time owned: 0 to 3 months
First a little background. As a radio tech in the USAF I spent two years on a HF transmitter site. The site had 12 10KW and 1 2.5KW transmitters, about 20 antennas. There was also a 15x24 antenna switch matrix. I've had to repair that matrix from lightning damage several times.

This Alpha Delta switch I acquired used, it had lightning damage. I opened it up to inspect the damage. It was minor and easily cleaned up. I found the switch to be a little poorly designed where the connectors are concerned and corrected that. The straps were too close to shorting to the case. The actual switch is of good solid design. The strap design makes ample contact for the power it is rated.
