I will be traveling to Ireland next week and will be taking my FT60R handheld and an Elk antenna. I purchased a short length of RG316 with appropriate connectors installed to avoid the need for several adapters and bulkier RG58. I was shocked at how small the diameter is for the 316. Manufacturer assures me it will work quite well at 145/435 for the use intended. Has anyone had experience with this cable? Tnx

I have not used that cable, but my coax calculator says at 435Mhz it has a 16.936db loss per 100 feet, or 9.65db loss per 100 feet at 145Mhz. A 3 foot section of cable would have a loss of .5db or 89% efficient at 435 and .3db loss or 94% efficient at 145Mhz. Probably work OK as long as it is a really short length of cable.

The loss compared to RG58 is about 2 times greater. But if you are typically runs about 5' or 6' lengths, then the loss is 2 X (next to nothing).
Expensive when you have connectors mounted for you. I've only used 174 which is almost the same with DIY SMA connectors to make much shorter WiFi cables. Now you have me thinking more about this. The HT already has SMA and SMA/BNC adapters are readily available to connect to my Arrow... hmmmm
