I hate to say it but there sure is a bunch of ignorance here concerning VHF antennas

Is yours different in some way? http://www.justpickone.org/skip/gall...onics&start=88 and the next page have pix of the current Metz antenna. Apparently, they've changed their antennae, as the MMSI, AM/FM and this Metz I have all have the type of connector shown, which is a discontinous thread. The pix of my holding the still-mounted-to-original-bracket antenna show that it's not long enough to mount with a nut, thus the extended connector I used... OK, I see what you mean. Apparently your angle bracket is too thick for the threads provided by Metz. There is a cheap and dirty solution to that kind of mounting problem involving Ty-Wraps and JB Weld that might just do the job if you're so inclined. I won't tell anyone as long as you don't look too closely at how my latest WiFi antenna is mounted at the top of our trawler mast. :-) |

I think the issue of cable value and what to get is over. Now it mostly depends on how much you value your life. And your passengers' lives. Easy decision. Maybe. --Vic |

If you are THAT worried, you shouldn't be on a boat. The percentage of times where 214 will save you and 213 won't is essentially ZERO. If you want to overspend on something meaningful for safety, look elsewhere. Maybe use the money to buy an extra handheld or an Epirb with better batteries. |

If you want to overspend on something meaningful for safety, look elsewhere. Maybe use the money to buy an extra handheld or an Epirb with better batteries. I just put in the "saving lives" to prod Skip. It can be valid though for the ultra-cautious. Plenty of other reasons to go with the best cable in the mast. Wayne's mentioned some. Did a bit of reading on it, and saw some comments that since the 214 is mil spec, the quality isn't spotty. It is with 213. This is interesting, though I won't swear by it. Might be relevant to mast movement though. http://www.mail-archive.com/repeater.../msg28257.html "The silver plating is what makes RG-214 advantageous over RG-213 in a duplex environment moreso than just the difference in braid coverage with respect to shielding effectiveness. Movement of the braid strands each other doesn't make nearly as much noise with the silver plated strands of RG-214 as compared to bare copper RG-213. And as the cable ages and the braid strands tarnish (oxidize), the difference becomes progressively greater as silver oxide is a very good conductor unlike cupric oxide (or is it cuprous, I forget, cupric oxide is black-ish and cuprous is red-ish IIRC." This is all voodoo to me, so I tend to listen to those with experience. Couldn't find anybody who would go with 213 over 214 except for price. Now, regarding price. http://therfc.com/coax.htm RG-213/U $ .68/ft $63.00/100' RG-214/U MIL $2.25/ft $194.00/100' $131 difference for 100' Up to the individual. Personally, I'd go the $131 just for the voodoo protection. Maybe I'm superstitious. Skip will do what Skip does. BTW, one radio guy gets his 214 from a mil surplus seller near his home for $.90 a foot. Not on the net though, and price hunting isn't always cost-effective. --Vic To be honest, I'd probably go for the 214 as well - "just because". I still don't think it would make a bit of difference as far as my level of safety, now or 20 years from now. The cable will be well protected INSIDE the mast and INSIDE the cabin. Very little, if any, will be exposed to the elements. Careful attention to installation and waterproof connections is what matters more than the differences between "really good" and "slightly better than really good". |

Maybe use the money to buy an extra handheld or an Epirb with better batteries. There is yet another way of valuing coax. If you get into a situation next year where a low-loss coax would JUST reach help, otherwise you perish, then you SHOULDN'T choose 214 or one of the more expensive ones still. There are lower loss, cheaper coax choices out there. Instead, 214 and the like are insurance against the day that may come in 12 years time, when the signal lines have taken a couple of knock-downs, and weeks of sea fog end in a call for help. THAT'S the moment when the cost earns its price. This year, you would get more range from a much cheaper coax, before time and weather take their toll.... Brian Whatcott Huh? What? |

Looks like a good place to buy.... Pulling up the attenuations next to each all came up with the same page. Perhaps I'm not understanding it correctly, but I can't seem to see the relevant categories, and the header is confusing, as it relates to per 100' but then seems to give different distances. If I ignore the header, I see 400 at 1.2, 8x at 2.5, 58 at 4.6, etc. Is it not there, or am I missing the 213/4? Thanks... |

But I've seen in multiple places that the 213 and 214 are identical on the electronics signal stuff. The difference is double shielding versus single, copper versus silver, implied longevity/signal degradation, and "guaranteed" quality - all in 214's favor. Price is in 213's favor. --Vic |
