2piece 2W SMA DC-Block DC to 6 GHz 50 Ohm

I needed these to help protect sensitive radio devices, but did not want to pay the high price the competition was charging. These are good quality and do the job.

I use these on satellite reception projects along with RTL-SDR units and LNAs. They help prevent voltage backfeed common with certain powered LNAs. I've been using one of these in an LRPT station all summer and have had no issues so far

Can't get too excited. They are just DC blockers but you do get 2 and they work as expected.

The ones i got are good. The return loss that I see could be due to a possible impedance mismatch. I see similar results with the Nooelec one.

The picture on Amazon clearly shows two (2) devices and there was only one (1) in the package I find this miss-leading and I needed two. I'm sure the device works, but only got 1/2 of what I thought I was paying for. UPDATE 6/10/2019: Company sent me another device and satisfied my issue. Picture still needs to be changed.

The product works exactly as listed. I use it with a converted SUP-2100 and a LNA4ALL wide-band amplifier, to isolate the bias tees from one another. Great product, prompt delivery.

Does just like it is supposed to. Built tough and does not fall apart like some others after installing and removing multiple times on my dual rtl-sdr setup.

This is a handy little component if you're working with RF signals and want to make sure no DC voltage accidentally passes through. It's essentially a capacitor in a coaxial package with SMA connectors. You just screw it in line with your RF cables. What I like about it is its simplicity and effectiveness. It does exactly what it's supposed to do – block DC while letting the RF signal pass with minimal loss. It's small, easy to use, and feels pretty robust. For peace of mind when connecting different RF devices, it's a worthwhile investment. Just make sure it's rated for the frequency range you're working with.
