I needed a way to switch two TVs between satellite and antenna when I moved the receiver for guests. Manually switching out the cables in my network/TV closet was a pain and also caused wear and tear to the terminators and splitters. With a set of UHF-type to F-type adapters this switch (2 of them, to be exact) works perfectly. It has a satisfying weight that speaks well of the construction within and without. The wide bandwidth of the switch means that there is no issue with my satellite receiver signal getting through intact. No noticeable signal loss at all. I have owned consumer-grade switches in the past. They look the same as they did in the 90s and I just don't think they are up to the modern task. Spent the extra (substantial) money and am very pleased with the results.

Works perfect for switching between antennas. Minimal losses in the switch. Heavy duty and much better than the cheaper version I tried first.

I use this coax switch on a 100 watt HF ham rig. The SWR is flat and switch action has a nice click to it. My old cheap switch literally fell apart on me. I have no worries about that happening with this switch. I do recommend this switch. 73 de K6WGX

This 2-way coax switch is great. It is extremely sturdy (after all it is rated for 1000+ watts). I totally trust it with my ICOM 7300 and antenna farm.The price was competitive and HamCity is a reputable ham radio provider.

Well built and durable, but when connected to the radio I saw a 3 watt drop in power and a higher SWR. Connection radio directly and my 3 watt power loss returned and my SWR dropped.

I ordered this product to switch between transceivers that share an antenna. Upon connecting the switch, SWR readings climbed unacceptably across the UHF and VHF frequencies. I tried several jumper cables and confirmed the switch was the problem. Further, SWR readings taken ahead of the switch are fine. Examples of increases are as follows:1.03 -> 1.41.3 -> 2.01.5-> 2.8I assume the unit is defective and have ordered another. I will update my review when I receive the replacement (which, annoyingly is taking much longer to ship than the original).
