WORKMAN/OPEK  Time owned: 0 to 3 months
You get what you pay for. Problem with this proverb it is worth a whole lot LESS than the $25 I paid. Maybe for the (4) SO239's and the knob...and the box....$6.

*output power dropped significantly
*on some freq's there was no antenna seperation. Couldn't compare receive signals.

Maybe I will rebuild it as suggested but I shouldn't have to.

JUNK!! Don't waste $$!  Time owned: 0 to 3 months
I bought this unit so I could switch between an omni and a beam on 2 meters. However, this switch reflected power back to the radio and degraded my signal. When I switched to the beam, my SWR was 3.5 and power output was only 10 watts from a 60-watt radio. When I eliminated the switch and went directly into the antenna, I got a 1.3 SWR with 60 watts out. Same results with the omni. Horrible quality switch. Unusable - unless you need a paper weight. Save your money to spend on a higher quality switch!

For receiver's antenna  Time owned: more than 12 months
I use this switch two years for receiver antenna and HF transceiver to 100 watts and VHF transceiver to 80 watts. For receiver - very good. For transceivers - interference induction between adjacent channels.

Piece of JUNK  Time owned: 0 to 3 months
I bought this switch on Ebay to use for 2 meters. When I hooked it up and used it the first time my radio showed a high SWR. When I took the switch apart I saw why. It uses regular electrical 18 gauge wire between connections. This is the type of junk you would see at a CB Shop. The switch says it can handle 1000 watts. Judging the poor quality of this switch there is no way it can handle any kind of power like that. Do yourself a favor and buy a good quality switch. Because this switch is a piece of crap.

Good for $10  Time owned: 0 to 3 months
I read all of the negative comments and decided to try one anyway for $10. It works fine, handles the power and is better that the one it replaced. If it starts giving me trouble, I will replace the wiring per the K2OWK tip.

I needed the way the Workman was arranged for my setup (input on one side and three outputs).

Only time will tell if it is a keeper but for $10 it is Good.

Just OK -- and only at low power  Time owned: more than 12 months
I have used these coax switches only with receivers. Isolation is poor. Construction and materials are of just average quality. I would not transmit more than 100 watts with one of these, and probably only use it to switch atennas to one rig - I would NEVER trust its isolation to protect a second rig from damage to its receiver front end when transmitting ANY amount of power through this switch.

For the money, about $12 street price, it is just a fair to good receive-only switch, but the below-average quality construction and materials prevents me from using it on transmit, and if I did, only to select one of up to three antennas, and never to isolate a second receiver/transceiver.

Just MY take. // James - K8JHR //

Not bad for the price  Time owned: more than 12 months
This switch has served me well. I have 3 of the Opek model CX-3 switches. They are not a Delta by no means. They are far better than MFJ. I have repaired and thrown out 4 MFJ switches. That is throwing money away. 1KW? I would only try that with my Delta 4. Have not had to open any of the switches so I don't know if it is full of cheese or what. The switch has screws not pop rivets so it looks like no big deal to get in side. If ain't broke don't fix it. It is a good product.

Fair switch if modified  Time owned: 3 to 6 months
I am giving this antenna switch another review. I have been using mine for a few months now. I have had no problems with it. I use a 100 watt transmitter. I do not think it would handle 1 KW, but I have not tested it for this. While the wiring is standard stranded wire it is a very short run and within the switch, and should make no difference in power transfer. It makes no difference in VSWR. In the way back days we used a knife switch to transfer antennas without problems. The only thing I did was to modify position three with RG8X coax to allow me to use this position for 6 meter operation. The switch is OK and I have had no mechanical problems with this switch.

Not worth even $10  Time owned: more than 12 months
One look inside will tell you this switch is not meant for transmitting. Isolation is non-existent. Plain hookup wire is used for the connections and the wires are too long and poorly dressed. The switch would probably be fine for a receive only setup which is the only reason I gave it a 1 rating instead of a zero. I don't trust it for transmitting. It's rated at 1000 watts! Give me a break!

Needs rewire to be good  Time owned: 6 to 12 months
I just bought one of these before reading the reviews on it. I opened the case after reading the reviews, and they are correct. The internal wiring is just insulated stranded wire, but for $10.00 you get 4 UHF connectors a nice switch and a good case. With some rework you can have a good inexpesive antenna switch. Replace the wire with RG-8X coax using the center conductor to the center of each connector throught the switch. Connect the shield to the connector ground of each UHF connector do not connect the other side of the shield and bring the unconnected shield as close to the center attchment as possible without shorting it. The switch will now have good isolation and handle about 300 watts. and will work to 100 MHZ or so.
