Review: Used for my Automatic Identification System on my yacht. Cable run from the top of the mast, down through the mast then through various areas behind walls etc to terminate at the nav desk. Good solid copper core makes the cable semi rigid but could still easily loop at around 100mm diameter.

## Questions & Answers

**Q: How high can the applied voltage go?**
A: I could not find the detailed specifications for this coax but for Belden 9258 RG-8X type the maximum voltage is 300 V RMS for UL (Unerwriters Laboratory). However, the Belden specifications also list 30 V RMS as a maximum voltage under "other". Coax cable is not suited for ACV. If you want to know about coax power handling capabilities, the RF power depends on frequency and how much power loss you can tolerate. Power loss heats the cable and the maximum power is 1000 W at 10 MHz and lower frequencies. At 1 GHz the maximum power is 60 W.

**Q: Why do you think swr depends on coax type or brand??? what is important is the db loss / 100 feet. please list that!**
A: SWR relates to matching the energy transfer between endpoints like the antenna and transmitter. The coax does not change the SWR value but passes it between endpoints. The higher SWR values produce losses in the coax which shows as heat. Larger coax conductors can handle more SWR losses, heat, than smaller coax like RG-58 and RG-8X. DB losses also show up as heat in the coax. 

If the coax cable changes the SWR the problem may be a damaged cable or  it's connectors or the cable is operating beyond its limits or someplace else in the system. Cable length or size does not change the SWR.

The 3 DB loss represents 50% power loss. The cable specifications list DB loss and SWR

**Q: What is the outside diameter of this cable?  assuming i can use lmr-240/rg8x connectors?   one post said it was about the diameter of rg58?**
A: RG-8X is the same size as RG-59 which is LARGER than RG-58 coax.
RG-8X and RG-59 need an UG-176 reducer to terminate in a PL-259 plug.
RG-58 will need an UG-175 reducer to terminate in the same plug.
SIZE DOES MATTER.

**Q: Is this able to properly withstand direct burial?**
A: I don't know the answer to that. I'm using the cable above ground, in a vehicle. Best to address that question with the seller.

### ⭐⭐⭐⭐⭐ Review
*by J***T on 23 September 2022*

The MOOKEERF cable solders easily and has the same specifications as the Times Microwave LMR-240 cable. but at a much lower cost. I used a MFJ 259 analyzer to measure the coax cable loss at 50 MHz and came close to the listed specifications. One caution: the MOOKEERF specifications are for 50 feet so the values must be doubled for 100 feet to compare to the LMR-240 specifications which are for 100 feet. The MOOKEERF cable has a solid core like the standard LMR-240 which is not the UltraFlex version. So, the cable is not as flexible as UltraFlex but has lower loss than UltrFlex. The cable construction appears to be similar to the LMR-240. This cable could be used at any length and frequency but the power lost in the cable could be high. I recommend using this cable for shorter feedlines less than 50 feet and at lower frequencies less than 30 MHz. The cable power loss at 100 feet and 50 MHz would be almost 30%. The specified 0.85 dB loss at 50 MHz would be close to 18%. A better cable choice for long feedlines and high frequencies would be XMR400 from XRDS at Amazon. This cable is only $26 more for 100 feet and the loss is half that from the MOOKEERF cable. Beware the XMR400 has a larger diameter and is very stiff. By the way, Wikipedia has a good article on decibels for power gain and loss but there is some math.
