I bought this coax before & used it. I needed more so I ordered 2. The cable received today is labeled "RG-58/U Coaxial Cable" no other markings. Male BNC on each end. This time I decided to "check it out" (non-destructive testing) using my MFJ-259B Analyzer and some of the advanced functions. Note: measurements were made using both 50 and 100 foot (2 connected) lengths. I am reporting standard 100 Foot measurements such as you would find in the ARRL Handbook. Z= 52 ohms... Velocity Factor 79.8%...
Measured Loss per 100ft...
...150 Mhz - 4.5 dB,
...120 Mhz - 3.9 dB,
... 90 Mhz - 2.6 dB,
... 60 Mhz - 3.3 dB,
... 30 Mhz - 2.3 dB,
... 10 Mhz - 1.4 dB,
... Remember that is loss per 100 ft. This product comes in 50ft lengths. Conclusion: A 100 ft run on 6 meters 1/2 of your power would be lost or about 3 db. A single 50ft length on frequencies 6 meters and below is very acceptable. Perfect for temporary or Field Day use. Even adding BNC to PL-259 adapters this is a great buy. My FT-817 backpack radio does not require adapters. On 2 meters 50ft is acceptable for temporary use with a gain antenna to offset loss. Finally I have run 100 watts into it. Keep your SWR low as good engineering practice and FCC rules require it.

Be forewarned the braid on this stuff is aluminum. Can't solder it. I got some for an antenna project, obviously it did not work out.

For your excellent technical review as well as your value judgment.It is not often that customers perform such a detailed, scientific analysis of the items A/E offers. Most of us do not have much sophisticated equipment to do this-I have only a multimeter... I invite such analysis by others-It's a definite help to all us"hams" 73's KD7KNC PS: From what I know, this is a real bargain!
Excellent cable for the price (found same price for a 6 foot BNC at RadioShack) and no impedance. Connectors are not cheap and neither is the cable. This is a steal at this price.
