Review: Great for a short run or cable extension in VHF work. - This was purchased as an extension for a 2M J-pole project whose original KMR-400 cable cable was not long enough. This works fine without adding significant signal loss in a basement station installation. Note that a SO-239 Coaxial Female/Female Adapter was required and is reviewed elsewhere. The cable appears to be very well made, but as it is stiff, it is best used in fixed installations where it is not moved significantly once installed.
Review: Good value - Save the money this works great. Low swr on all my antenna’s. I have used this coax in different links and it always comes out well. I have used jumpers that are 1 foot long 6 foot long 35 foot long and the 50 foot all at great SWR results and just well-made.

### ⭐⭐⭐⭐⭐ Excellent value
*by O***O on May 27, 2025*

This is a 400 type of coax and loss it is exactly as it should be for 150 foot length. This and 2 m dipole are going 80 feet up into a tree and over to the house. Quality seems good an excellent value compared to other coax. Update - it’s been 7 months up in the tree and doing great! Loss at the antenna is in acceptable range for 400 size coax! Very good buy.
