Yeah, that’s a few tons of wood right there. Glad it didn’t do any major damage.

Here ya go, gives you a bit of an idea what sort of antenna’s are where on a modern airliner. Note that some of these operate on a shared frequency so they do not operate continuously but have controller that pauses transmissions so that they all can share.

And I thought the A-10’s radios were complex…
Our HF broke on the only PC-24 that is equipped with it.

Despite all the issues with inner city infrastructure in the Rhine-Ruhr region there is some great bike infrastructure in certain places, but more often than not you really need to know the city to find these jewels.
Of course things like the RS1 - basically a bike highway that’s supposed to go all the way from Duisburg in the west, and even connecting the left Lower Rhine further west, to Hamm in Westfalen in the most eastern extent of the Ruhr-Area - have made barely any progress over the years. Only some short sections have been build, the longest one between Mülheim and Essen, and there’s doubts wether the project is ever going to be completed. The progress is laughable and stands in no relation to the costs, mostly because of politics.
For example most of the route for the RS1 is supposed to follow old railway tracks that are no longer used but in Essen a politician wanted the elevated bike path to go right through houses in a new development instead of just using the existing railway embankment. His plan was to remove the embankment for the new development. It’s insanely expensive, won’t happen, has stalled the project for years and now that whole section is questionable and might just become a gravel section instead of the planned 4-5m wide paved bike path. All the money spend for his fairy project could have been used to complete a decently sized section of the RS1…
It’s a shame bike infrastructure gets so much pushback at the moment. Ironically it’s from the same people that curse at cyclists using regular roads, mostly for lack of alternatives. Conservatives in Berlin for example have cancelled almost all big bike infrastructure projects and are planning to open the inner city more for cars. It’s insanity.
I take inner cities without cars over car-centric cities any day of the week. I don’t even know why you’d want to drive a car in Berlin. It’s a horrible experience and Berlin’s public transport is superior in every way.

I commute 25km through Berlin. Public transport takes 80 mins when there are no issues. During this summer it more close to 100 min.
Bike is roughly the same (excluding the necessary shower and change of clothes). You can’t really go faster than 20 kph on average due to traffic lights and slow bikes on narrow bike lanes.
Car takes anything between 30 mins and 2 hours. On average it’s 45 mins for me. This summer closer to 60 mins.

Doesn’t sound fun. Bike paths that radially connect the suburbs to the center and branch out along the way sound like a great idea. I have only ever visited Berlin, once on a bike, although my cousin’s live there and they only use public transport and bikes, it probably depends on where you live and work.
On my commute, on average, I am about 20min slower on a bike compared to a car. In the evening I am 30min slower, in the morning 10min slower at most, sometimes faster. That is on a 30km route with decent bike infrastructure. Public transport is horrible to work and would take me almost 2h

Good lord, what’s the holdup? 30km by rail in Tokyo takes 33 minutes, including dead time between transfers.

It is Berlin, that’s what is wrong.

Ah, antenna or controller box? And let me guess, no parts available at any supplies short of OEM backorders?

Actually…both…at one point. The antenna is supposed to be replaced I think it is every 500 hours or something crazy like that. We already had one break. They fixed that…but now it is the Honeywell radio itself (the avionic module in the rack) that isn’t functioning correctly. Honeywell isn’t super quick on finding a replacement…or they can’t find one. Overall, the parts supply chain for the Pilatus seems to be variable in quality. Still better than the ancient parts that the Citations were getting (remanufactured…they would test fine and then fail within a few days of being installed…sent back for another reman unit…repeat and repeat…)

How does the Pc24 compare to your citation for mission readiness and downtime @BeachAV8R (dont get yourself in trouble, just curious if its reliable so far)

We took our HF off as the 560 fleet was seeing coax cables (and occasionally the entire antenna!) break loose and beat up the airplane. Just went through recurrent with a crew that had it come completely loose off the tail and beat the airplane to death! 
Never use it anyway for the routes we fly, and have iridium anyway. Know what you mean about Honeywell parts, and some Citation parts. It’s getting better on the Cessna side, almost back to pre-covid.

That sounds highly worrying, how did the antenna get loose in the first place? And the Coax cables shouldn’t get loose like that…
I suspect icing causes the issue, but that’s entirely speculative on my part.

I probably shouldn’t answer that. You can infer something from that.

It broke at the “turnbuckle” I believe where it attaches to the vertical stab. I did notice that the new one has different colored tape or wrapping around it…so they may have changed the design perhaps. Only one of our three PC-24s is equipped with the HF radio and antenna…typically the only time we use it is going to Bermuda. Last time I went to Bermuda (last year)…broadcast quality on the was out was about 3x3 and on the way back we could not raise ANYONE with the HF and resorted to relaying position reports via 121.5 with some other aircraft. Not ideal.

It’s worth mentioning that I had an HF antenna break on the Citation once many years ago. We didn’t even know it had parted until we rolled up on the ramp in Wilmington and the line guy that parked us (it was night) was waving his wands kind of frantically. We shut down normally and he told us something was wrapped around our right engine. Sure enough…went over and the antenna had broken at the fuselage mounting point and had whipped back over the left engine…kind of resting across the left engine pylon. Surprisingly…it did no damage. I could only imagine what would have happened if that cable had actually gone INTO the engine… 
Also happy that it didn’t somehow lodge into the elevator… There are all kinds of things I wouldn’t want happen with a metal cable whipping around behind the aircraft. One of those lucky things that nothing happened.

One of the jobs I did in the Army, HF was our primary means of comms. That secnario was situation normal.
One time, even though our Platoon HQ was ‘only’ 150km away we were relaying through another unit that was nearly 2000km away.
The crazy thing was that was after trying multiple antenna configurations unsuccessfully, we had an Inverted V dipole (half wavelength) that was oriented to the East (our HQ) and the relay station was nearly due North - HF antenna theory suggests that isn’t possible… or at least very unlikely.
