Page Name : Type F Coax Connector
[edit]This article really should be renamed Type F Coax Connector to alleviate confusion. The connector is not really suitable for non-coax type connections aka high power DC or AC mains current. There are systems that pass AC and DC electricity (by what standard I do not know) via this connector but only a few units designed for the cable television trade seem to use them.

Dubious passband in infobox
[edit]The infobox lists a pass-band of 0-1GHz for F connectors (without citation), but these connectors are used universally with RG-6/UQ cable for the IF connection from LNBs to STBs in satellite TV, where the operating frequency is 950 - 1950MHz (or occasionally 2150MHz), so it is unlikely the passband is that low (or everyone's DTH satellite systems wouldn't work). — Preceding unsigned comment added by 27.252.76.236 (talk) 10:37, 25 November 2013 (UTC)
According to this spec from amphenol-connex, it has a "max freq" of 2 GHz. http://www.amphenolconnex.com/222118.html However, I strongly suspect the passband is model-dependent and is strongly influenced by the quality of the RG-59/RG-6 cable used in conjunction with the connector head. Also, "max freq" isn't well defined in this case (e.g. is it distortion or attenuation limited?) What you really want is a VNA plot and a TDR of the connector's performance to capture the subtlety, so I'd phrase the performance of the F-connector as "specified for use up to 2GHz for some models". — Preceding unsigned comment added by 210.23.18.169 (talk) 06:16, 13 August 2014 (UTC)
Europe
[edit]I'd like to see more information about the European version of this, which I believe is called the IEC antenna connector (also known as the Euro TV connector).
- The connector used for PAL (Europe, Australia and others :) should be properly termed "Belling-Lee connector". See this page for details - http://www.megalithia.com/elect/bellinglee/
- And it's not the "European version" of the F-connector - F-connectors are widely used in the UK at least for satellite and cable connections. The Belling-Lee (not widely known by this name; more usually "tv aerial plug" etc) is used for conventional RF from aerials and as a lowest-common-denominator interconnection with videos and set-top boxes of various kinds.
- Yes, in Europe we've been using the F connector for analogue satellite TV. 79.193.60.126 (talk) 22:53, 4 January 2012 (UTC)
DAB radio sets
[edit]Lots of DAB radio sets seem to have adopted the F connector for external aerials.
Push On F connector
[edit]The article mentions poor shielding of Push-on F connectors. This is incorrect.
While I can not say with 100% certainty that poor shielding Push On F connectors do not exist, I am quite sure the author confused the Push On F connector with the "screw on" type F connector. This "screw on" type is indeed known for its poor shielding and low reliability.
Here in the Netherlands very high quality (NLkabel certified) Push On F connectors are being used. — Preceding unsigned comment added by Paulmathot (talk • contribs) 11:43, 10 June 2011 (UTC)
As long as the connection does not come loose, than there should be no issue with shielding. I wouldn't categorize it as poor, but there not as much metal shielding as a typical connector. Also it easier to become loose than a typical connector. On the plus side, they are easier to use. -Cable Tech — Preceding unsigned comment added by 204.235.114.167 (talk) 16:55, 1 November 2012 (UTC)
Name
[edit]Why is it called an "F" connector? How did it get this 'name'?13:11, 30 July 2011 (UTC)Fredquint (talk)
Not computer related
[edit]Why does this come within the scope of WikiProject Computing?
- This connector is used on consumer electronics most notably TVRO satellite equipment. It is not related to computing in any way which probably explains the low importance rating.
Phrogworx (talk) 09:52, 16 August 2011 (UTC)
- Agreed and pending any objections I am going to remove the classification from it, and petition to reclassify it as a Wikiproject:Telecommunications article. It fits best there. NECRATSpeak to me 05:10, 5 September 2012 (UTC)
- How about WP:ELECTRONICS or WP:TV? --Kvng (talk) 13:21, 5 September 2012 (UTC)
male female tech terms
[edit]The cables for this usually have male connections on each end. Please add pictures and details for the standard mating female jacks. Also mention female-female adapters for mating two cables? And if an extension cable did have a female end, what would be the technical term for that connector?-71.174.181.102 (talk) 21:52, 9 September 2013 (UTC)
Inherent
[edit]A chocolate cake can be made "weatherproof", too. But it's not "inherently" weatherproof. The extra word is just extra baggage. --Wtshymanski (talk) 00:23, 4 December 2017 (UTC)
Not necessarily. A chocolate cake can indeed be made weatherproof. A well-made camping tent is inherently weatherproof. There is a distinction. I take umbrage at the word "proof" because it would be physically impossible to encase a chocolate cake (or construct a camping tent, for that matter) in a manner that would leave it unaffected by weather indefinitely. Heck, I take umbrage at "weather" as well, because what might be weather resistant in a light drizzle may in fact fail during a cat 5 hurricane. And what we're really talking about is water resistance specifically, not all manner of weather. But I suppose we have to draw the line somewhere. 96.56.144.166 (talk) 03:12, 30 April 2021 (UTC)
And that's to say nothing about the fact that water/weather resistant measures such as those described in the article these connectors are rarely employed by the cable TV industry, particularly at customer premises (e.g. grounding couplers at the service entrance, splitters mounted to siding, etc). If anyone submits a creative commons picture of a cable TV tech at a single-family dwelling enclosing their connectors in an housing, using any manner of grease, or even "weatherproof" (ahem) o-ring-equipped connectors, I'll print out these words and eat them. Point being that, while these connectors are not inherently "weatherproof" (ahem x2), they will often withstand a couple of decades of weathering without issue. Not sure why water resistance was discussed twice in the article, and in the general description section above the fold, no less. 96.56.144.166 (talk) 03:12, 30 April 2021 (UTC)
Metric Conversions
[edit]The threads on an F connector are 3/8‑32UNEF. This has a nominal outside diameter of 9.525mm, but there is no functional metric conversion of the thread. If you need to tap a hole, you need a 3/8‑32UNEF tap. The hex is 7/16" across the flats, not 11mm. You are selecting a wrench. [1] I have not verified that the hexes are invariably 7/16". Unit conversions of regular lengths are acceptable and appropriate. I am concerned about the specification of tooling.JHowardGibson (talk) 06:25, 8 April 2021 (UTC)
- Unit conversions on Wikipedia are refreshingly free of the ravages of common sense. There's no point in metric conversions of a thread spec that is only defined for inch units. Few now remember the unit-conversion fixation of "Bobblewik" from years gone by. Please stamp out inappropriate conversions when you find them. --Wtshymanski (talk) 05:00, 11 April 2021 (UTC)
- I am staring at that description. A correct thread specification will be better, but not much better. You really need a drawing. Can I upload a PDF file with the CAD file I used to generate it?JHowardGibson (talk) 17:25, 12 April 2021 (UTC)
- Probably undue emphasis for this article. Even giving the inch-dimensions thread spec is probably more information than the average encyclopedia reader can use. No-one is going to set up shop manufacturing anything based on the erratic information of Wikipedia. This isn't supposed to be a parts catalog anyway, though we love to expand each little Pokemon and transistor number into what we light-heartedly refer to as "articles". At most give the inch-dimension thread spec (unless the authoritative standard gives metric dimensions), and let the metric bigots stew in their own bile. --Wtshymanski (talk) 16:19, 14 April 2021 (UTC)
