The coax used for most F connections also has low wattage capacities. It's great for low wattage, high frequency like satellite apps though. All test equip uses BNC for the ease of removal, high stability, strength and wattage ratings. The missiles I worked on in the USAF (air launched nukes) all ran in the Ghz ranges and were connected by either threaded UHF style connectors and BNC. All MILSPEC items are more expensive due to the fact they are generally custom built and nonstandard. When it comes to commonly available items, the MILSPEC items are generally built to a higher rating or different than the common ones in durability. There's noting like having a cheap Taiwanese cable when you're out in the middle of nowhere doing an alignment on a radar unit in the elements. Many of the diehard ham radio people I know refuse to use the generic junk available and will wait up to a year to find surplus at dealers and government auctions. I'm not that fussy with ethernet since we aren't talking about a lot of energy in watts or frequency so the common BNC's work for that. The cables I use for my scopes are surplus MILSPEC though. I had an Artisoft setup known as "Simply Lantastic" that was ethernet/thinnet and came with it's own NE2000 cards, but instead of tees, BNC's and terminators, they used 1/8" phone plugs and two earphone jacks. The earphone jacks switched the terminators in or out as needed so it was auto-magic when the cable was removed. Bad thing was the plugs were prone to being pulled out slightly and not making a good connection, and therefore a nightmare (at first) to figure out for troubleshooting.
