RG142 BNC Male to BNC Male Coaxial Cable 6FT 50 ohm Ultra Low Loss for Antenna, RF Radio, Modem, Oscilloscope, Spectrum, Analyzer, Signal Generator

These jumpers are braided multiple shielded with solid center conductor. The BNC PL-259 plugs have the correct 50 Ohm center insulation and pins. These are NOT 75 Ohm jumpers for video. These are jumpers for ham radio, lab and RF use. I did not test these jumpers rigorously, but they’re OK for bench use up to at least 200 MHz. I believe they could handle higher frequencies without much attenuation. The shielding is braided, no foil. Generally no foil is better suited foes power handling applications. There are RTV filled strain relief boots at each end.I’d say the greatest drawback is the construction of the cables makes them fairly stiff. These jumpers aren’t quite as nice as Pomona, but they’re about 1/5th the cost. I’d be willing to buy these jumpers again.

This cord is solid, it's made of good strong material and its stiff. It is worth the money if you need a short run.

perfect to the application we are using for to replace those ugly metal antenna's and get some range on your gear.

I've only used it at HF. Checked quickly with nanoVNA, loss was low enough.Seems rugged

This 10 ft long MOOKEERF BNC Male to BNC Male Cable seems to be made well. The cable looks like RG142, with the right diameter, transparent color and dense silver outer braid.I took measurements with a VNA. The transmission loss chart shows it to be better than expected for a 10 foot piece of RG142. The chart shows peaks and valleys that are due to the cable length that the VNA does not compensate for. The actual loss is about in the middle of the peaks and valleys. So, at 3 GHz, the loss is about 2 dB vs the expected 2.4 dB loss of 10 ft of RG142 at that frequency.The return loss chart also has peaks and valleys due to the same issues and the actual numbers are again in the middle. The return loss at low frequencies is about 40 dB, which is excellent. It decreases to about 27 dB at 3 GHz, which is pretty good. Even the peaks of 18 dB or so are pretty decent at that frequency.

Good quality need more color options.

For some reason, I thought RG-142 was more along the line of RG-316 or RG-174, but I was wrong. I've been testing this jumper over the last week with my ham radio QRP rig and strangely enough, I've been hearing fewer birdies, less interference, and get better reports than I did using RG-316. Keeping in mind, this is being used between the radio and the tuner, and from the tuner to the antenna is RG-8X. The heat shrinking impressed me more than I thought it would. The manufacturer used some really good, self-sealing heat shrink that doesn't move at all and so far has held very firmly in place. The cable itself is a solid wire core, but is still flexible enough to maneuver it were needed. Overall, I'm impressed with the build quality of the jumper and when it comes to radio gear, I can be overly critical so, that's saying something.

This coax meets specs, I've never had a cable from MOOKEERF that didn't. The ends have the heat shrink for strain relief as pictured, which is more than some other cheap brands.I did ding a star as the text description in the item title isn't 100% accurate. It says its black cable, but it is indeed copper colored translucent like what is in the picture. I like MOOKEERF products, but they do need to improve their proofreading of item listings.
