Submarines could receive HF signals at shallow depths (approx. 60 feet). LF signals could penetrate much deeper. Could a towed antenna body be employed which could support a receiver antenna for much higher frequencies? The survivability of such an antenna would be an issue.
Towed antenna would be an option but you are absolutely correct in regards to the survivabillity., due to other subs or obstacles in the water. Thanks for watching.
That’s correct . Although new radio technology 2.4ghz/ 900mhz is providing the best of both worlds. The 2.4ghz provides the range while surface running as well as telemetry and the 900mhz provides the penetrating power for submerged operations. Most of our group is still using the MHz equipment, but as it starts to fail and availability is very limited we will probably all gravitate to the 2.4ghz/900mhz equipment.
Interesting, I was going to ask a similar question. I fly fixed-wing RC planes primarily; started off in the early 1990’s on 72 MHz (when I was initially learning to fly RC), then moving to the 50 MHz. amateur band since I’ve been a licensed radio amateur from 1969; using the 50 MHz. ham band meant that I rarely had to wait for an open frequency back in the days when a frequency board & clothespins were standard practice at virtually all RC aircraft fields. (& woe betide the careless RC pilots who switched on their transmitters blindly & “shot down” someone’s plane! Besides a getting a “bad rap”, virtually all RC clubs I belonged to had a rule that if you “shot down” someone else’s plane that way, you were FINANCIALLY RESPONSIBLE for replacing it!). Now I fly on 2.4 GHz. Digital spread- spectrum like everyone else, mostly park - flying small or micro planes; when I did return to my old RC club after a few years, it was interesting to see that the old frequency board had been retired! Since it seems like RC submariners use 2.4 GHz. only on the surface, how deep can you safely dive on 900 or 75 MHz.? I’m also curious on radio range when operating submerged; how far distance is reliable? BEAUTIFUL models, by the way! 😊
I can’t speak for the dual band radios from experience as all of our group is still using 75mhz , as far as range while submerged I typically can go out about 40-50 yards at periscope depth without any problems. Hardest part is keeping a visual on the boat. Once closer to shore I can run up to 6 feet deep before my fail safe kicks in and automatically surfaces the boat. I would imagine the dual frequency radios would have the same limitations.
Unfortunately, we don’t have a listed schedule. We typically meet every Sunday morning at this location pending on no events being held by the aquatic center and of course weather. No worries, we will be meeting again this Sunday. Thanks
Best video work of its kind on the Interlink today! And these subs are so well dialed in. Wonderful work all around.
Thank you! Glad you are enjoying the videos.
Fantastic job!
congratulations!
Thanks a lot!
How do they stop the water from leaking in ??? Very impressive guys ! Thnk u for sharing ! 👍 ❤❤
Thanks for the question. Most Water Tight Cylinders and dry hull boats use a variety of seals, O-rings, cup seals, shaft seals and bellows seals.
@@LG-RC ok, thnk u, bit above my paygrade !! Haha 🤣
this video made me sub goob job❤❤❤ from Alberta Canada

Great job! Those look like mhz Tx antennas. Does 2.4 ghz not penetrate the water sufficiently?

nice
Thanks for watching.
When is the next meet? I'd love to come check it out
We will be meeting this Sunday morning, and we set up just left of the Nimbus Flat boat launch. Come check us out. Thanks for watching.
@@LG-RC Thought i'd be able to make it out. is there a schedule listed somewhere? fb page or the like? Thanks

這些3D印刷件會開源嗎^^
Can you be more specific on what 3D printed part you are referring to? For the OTW?
Let's go 😂❤❤
Thanks for watching.
