Daiwa CS-201A 2 Position Coax Switch

Well made and works very well.

Just doing exactly what it supposed to do with low signal loss with 70ft of LMR 400 great product well-made

I use this switch to have my 2 ham radios share one antenna and it works great. Comes with mounting hardware that I used to bolt to my desk.

Ive owned several coax switches since becoming a radio amateur operator in 1974. I bought my first Daiwa switches several years ago and I have been pleased with their heavy construction and dependable operation. The first Daiwa two position switch is still in service working with a Daiwa four position switch (see attached picture). The four position switch selects the radio (two HF radios, including one with a VHF coax connector, and one VHF mobile) and the two position switch selects the antenna (the outside position is controlled by a five position Ameritron antenna selector and an inside two meter magnet mount antenna. The inside two meter antenna is almost exclusively used as a dummy load in case I inadvertently transmit when the outside HF/VHF antennas are off line. In case of thunder storms, I still physically disconnect the outside coax. I live on the Cumberland Plateau in east central Tennessee, which is characterized by unusually violent thunder storms. I routinely run a 180 watt VHF amplifier and 600 watt HF amplifier, both well within the capabilities of the switches. The second Daiwa two position switch was purchased for another room to switch an indoor multiband antenna with an outside VHF/UHF antenna. It precludes me from having to disconnect the coax when the radio is not in use. Again, I normally disconnect the outside coax at the connector during lightning storms. I have followed this practice for decades and have yet to loose a radio due to a lightning strike.

So strong, weighs so much. Manufactured to last, great connections. I want to buy 4-5 more.

The switch works fine and I would recommend it.

I thought it would be less expensive But it is really well built!

I have older versions of the same switch and no change in quality which is very good. VHF/UHF losses within spec.

Great product and good quality

Good SHORTING coax switch. Contrary to some reviews here, the version of the switch I received does indeed short the center conductor of the non-selected connector (port) to the switch case, and hence to the coax shields of connected cables, and to ground if the coax switch case is grounded, as it should be in many installations.. Tech data on any of the major ham radio equipment supplier Web sites will confirm this. In many cases, this shorting is good, but may not be appropriate if this switch is used to connect one of two transmitters to an amplifier, antenna tuner, or antenna - keying a transceiver transmitter into a short circuit will be hard on your transmitter final amplifier - unless you like the hassle and cost of replacing final amp transistors :)
