| Jan 27, 2016 at 23:54 | comment | added | aeroalias | @reirab Yes. I meant the external wire antennae. They've been shifted to the vertical fin, it seems. | |
| Jan 27, 2016 at 21:36 | comment | added | user2896 | Apparently, for smaller planes the HF antenna is something that one could spool out. A Cessna 150 flying across the Atlantic includes a bit about it not working (it got tangled). "The 150 had also been fitted with an HF including an antenna tuning mechanism and a trailing aerial." --- just to get another idea of that antenna on other planes. | |

| Jan 27, 2016 at 20:13 | comment | added | reirab | When you say "newer 737s don't have these," you're referring just to the long external wire antennas, not HF antennas in general, right? AFAIK, nearly all airliners still have HF antennas for the purposes you mentioned (i.e. trans-oceanic routes and such.) | |
| Jan 27, 2016 at 17:12 | comment | added | aeroalias | @user2357112 Thats wierd. There seems to be no problem for me. Anyway, see this. | |
| Jan 27, 2016 at 17:09 | comment | added | user2357112 | @aeroalias: That page seems to require an account to see it. Do you have any references that don't require an account? | |
| Jan 27, 2016 at 14:08 | comment | added | aeroalias | @ROIMaison Yes. The new antenna looks something like this | |
| Jan 27, 2016 at 12:34 | comment | added | ROIMaison | So the wire was a part of the HF antenna? And the newer version don't need this wire anymore? | |
