TW-102 2 Position Coaxial Switch for 144/440MHz HAM CB or HF/VHF/UHF Radio UHF Female (SO-239) Connector Plated Golden

Have this to switch both my antennas from their transceivers over to a pair of SDR devices. Good solid switching mechanism. I was worried about dumping power into my rspdx when transmitting FT8 on HF, so I measured the capacitively coupled power when transmitting. According to my TinySA, there's 78dBm of separation between TX and the disconnected terminal.The rspdx I have has a max input power of 10dBm. That's 10mw. My HF rig will do 100W, and that's 50dBm. So in theory to be safe, I'd want 40dBm of isolation or more. This switch gives me an additional 38dBm of isolation. So my SDR gets 1 microwatt... I can rest easy that I won't blow up my SDR.

I've used the device now for almost a week and a 1/2 and have found it to be quite efficient. I'm glad I made the purchase.

I did a lot off research on these before I bought this one. Most of what I saw did not hold up well this is made of metal and heavy duty works very well highly recommended

This switch is really well built. I expected it would work just fine. But when I received it and felt how heavy it is... Wow!! This is really nicely made!

Works perfectly. Good solid construction.

100% satisfied with the product. Will recommend. Did a Frequency sweep from 400Khz to 500 Mhz with less than 0.5dB loss.

These are nice switches. I bought two for ham radio. They’re well built and work good.

Works excellent
