Bolton Technical | Bolton400 20 ft Coaxial Cable | 50ohm N Male to N Male Connector | Heavy Duty, Ultra Low Loss Coax Cable for Signal Booster & Antenna Installation | Indoor & Outdoor Use (Black)

These are great low loss cables with solid 75 Ω "N" connectors!

Excellent antenna cable. Works great for my radio installation.

The coax is working out exactly what I was looking for… very good Transfer from Antenna to Radio.

I have the Wilson Electronics "WeBoost" cell-signal amplifier for my farmhouse. I wanted to spread the signal to other areas within my house with a splitter and auxiliary interior antennas. BUT, their cables are expensive! So, I decided to try the Bolton400 Cable -LMR®400 Equivalent Coaxial Cable with male N-connectors. It feels just as sturdy (stiff) and heavy duty as the Wilson Electronics cables and seems to work just as well for my 50 ohm setup. Therefore, I bought a few more to complete my setup and am VERY PLEASED with the results. Now, these cables are thick and stiff and well shielded. If you have an application where rounding tight corners is necessary, this may be challenging to install. My application was laying them out in my attic and down to a couple of ceilings on other floors, so the stiff cable worked fine for my layout and the shielding protects the signal. I would highly recommend this product for the quality, functionality, and variety of lengths offered.

Works great for my cb base station! I wish I would have bought a longer cable.

Originally bought this cable to use in the base HAM station with the deployable antenna in 2 meter band. This cable type is an equivalent of the LMR400 ( .401" thick with, I believe, dual shield and supposed to have a direct burial rating) which is a modern replacement for the RG-8/U. The good news is that is it is more or less up to specs, the insertion loss measured with NanoVNA SAA-2N is -0.5 dB with the expected specs value -0.45 dB at 146.52 MHz. The characteristic impedance is 51.3 Ohm which is borderline but passable. One of the downsides is that it is, as previously mentioned in other reviews, is fairly stiff and I expect it to be cumbersome with the deployable antenna on a telescopic mast that I am using (especially in cold season when it will turn into a stick). On the other hand this is perhaps the only cable of this class under $2/foot that I've recently seen. The bottom like is that for the base stations with permanently mounted antennas this is a good option. For deployable solutions this can be a balancing act.

I purchased this cable to rewire the antenna on my sailboat mast. The mast is 33 feet long. Add that to the cabin penetration harness and I needed almost the entire length. I put ends on it to match what I needed (not what ships on the cable) and I was all set. Tested it with the radio at the end of the wire, and with the mast laying below the treeline on sawhorses got solid marine weather forecast and quite a few boaters who were likely coastal on the radio. I was at Gibson Drydocks in San Mateo Florida, many miles from the coast as the crow flies. Normally I would not have thought this odd, but the mast was laying sideways about 3 feet off the ground inside a TON of thick tree and vegetative growth wall. That means reception through this cable is definitely going to be great when the antenna is 43 feet in the air and on the coastal ocean area, maybe holding signal from one source or another all the way into the Carib. but getting me out nice and strong all the way there too. Of course, there are laws of physics in play, but I have no doubt that if a signal can be obtained or sent under those laws, this is going to be far superior to the RG-8 that shipped with my sailboat when she was new. The power rating of my output from the radio will be far higher than the RG-8 allowed as well. The cable is far stiffer than the old stuff, and I was careful to install it with minimal bends. It did wrap once around the crosspin in the top of the mast (to hold it in place without strain on the antenna mount or chafe on the hole where it leaves the mast wall) but I added a couple layers of thick heat-shrink tubing to the chafe points just in case something tried to rub a hole (the prior wire which appeared to have taken a lightning bolt had several places where the insulation had worn all but through due to chafe). I do not think I will be likely to replace this cable during my lifetime or at least during the time I have this boat. Installing the ends was probably the most challenging part of the operation, and that was still not that bad. You may be able to get conversion connectors to do it without changing the originals out, but I was concerned that I did not want to get signal loss from connections. The incredible retention in signal was part of the reason I went with this cable to begin with, as I had 2 full spools of the other wire on hand and already paid for when I purchased this wire to use instead.

Great quality cable. I use these up to 450 MHz with very low loss.

I've been an amateur radio operator for 45 years and I know that if you are operating on UHF you need LMR400 coax. I operate a UHF digital repeater for DMR radio and I wanted to make sure the best coax feedline to run to the top of my 50 ft tower. After looking at all the radio sources I could find I came across the listing on Amazon.ca. This is the best price I could find for LMR400.
