Very Poor  Time owned: 0 to 3 months
A local ham friend of mine got me a new Opek model CX-3 1000Watt coax switch at a recent hamfest. I hooked up the switch to my 10,20 and 80 meter antennas with my Yaesu 857D running at 75 watts. Well, it didn't tune up correctly on 80 meters exhibiting a very high SWR which the tuner could not lower. I tried it on 10 meters and it's tuned with a 1.8 SWR but power was reduced significantly according to my Siltronics watt meter. A look inside shows small gauge wire and hasty routing and soldering of same. This leads me to believe that in spite of the switch setting, RF is leaking to the other two antennas. It is labeled at 1000watts but it can't handle 75! It would probably glow in the dark at 1000 or just go "POOF"!

I am disappointed in this product and my friend is embarrassed!

Avoid at any price!

I should have known better.
This switch shows "You only get what you pay for"

I broke down, spend the money and purchased Alpha Delta switches. Good investment and I am sure they will outlast me!

STAY AWAY!  Time owned: 0 to 3 months
I purchased this switch off of Ebay, only looking at the price tag. I intended to use it to switch between my FT-857D and a CB. When I tried using my FT-857D on 52.525 through this switch, the power was reduced to 50w. Extended keying down on this frequency also appeared to heat up the switch. I've scraped this POS and went with an MFJ 4 pos switch (MFJ-1704). I should really know by now that cheap price isn't always good.

Fail.  Time owned: 0 to 3 months
This antenna switch violates nearly every possible law of RF design. Losses and crosstalk will be incredible above VHF. The unit will likely flash over LONG before you approach its supposed 1000 watt rating!

The wiring inside the switch is excessively long and sloppy lengths of 18 gauge PVC insulated wire with really melty, burnt insulation, like you'd find in a bad Chinese lamp. In places, it runs right together, ensuring nice capacitive coupling to unused ports!

The switch itself is a rather awful little rotary switch that is not designed for RF use. The contacts are diagonal strips of metal that sit very close and parallel to each other - that's right, more capacitive coupling. A proper antenna switch has a lot more separation!

What would this switch be good for? Switching between different signal sources to an HF *reciever*. What is this switch not good for? ANYTHING ELSE. This thing's likely to flashover and take our your transmitter, or feed signal from a transmitter right into a receiver and blast it to bits.

ummm well??  Time owned: more than 12 months
i agree these are not the greates switches.i own 2. both are for 2 meter rigs,and work ok. the little ball bearing inside falls out the race sometimes,so i took it apart and greased it with dielectric grease.,and now it works ok,but it does bleed over into other postions. if i have it in the off position,you can still hear signals easily. for 10$ ok. spend extra and get a good switch
