Ham Radio - The giant Collins HF discone antenna at the Titan Missile Museum.

[@robstewart5995]

I had the pleasure of transmitting from that antenna in June of 2022 . What a thrill, It was a beautiful crisp day and stations were coming in from Europe and I spoke to stations across the US that antenna seems to be a great receiving antenna With all that steel up in the air. Thank you Green Valley for taking care of that fantastic antenna.

[@bentrider1972]

My mother worked at Collins here in Cedar Rapids in the late 60's right out of high school till she retired around 88-90..She showed me how to solder and what not..So you could say Collins taught me how to work on my radios 🤣

[@kirkgoins7214]

I was a Titan II Launch Crew Member at Little Rock, AR 76-81. I can remember using the HF Radio in the wee hours of the night to listen to all sorts of stations from all over the world as we had no requirement to actively monitor a specific freq most of the time. Thanks for the memories...

[@loughkb]

Standing in there, I was thinking about the crews and how they'd pass the time. I imagined them tuning around the shortwave bands, listening to various stations for entertainment during the idle hours. And you've confirmed my thoughts. :-) That antenna sure hears well.

[@NickFrom1228]

Wow, during the Damascus explosion. That must have shook things up for a while. I'll bet there weren't loose sockets used after that...

[@kirkgoins7214]

@@NickFrom1228 IF the tech had properly positioned the heavy rubber material correctly on the platform, that socket should have hit that and rolled on to the platform and not fallen between it and the missile. BTW The Orion capsule's engine and thrusters use the same fuel and oxidizer as the Titan II did.

In Sept 2021 in 106 degree heat I set my IC-7610 up attached to my running mustang so the battery wouldn't die and talked to my buddy in Washington state for about an hour and 20 minutes. 20 and 40 meters worked great!

Thanks for the video. I was wondering what an HF discone antenna would be like. Looks very cool!

[@MG.50]

THANK YOU ! That was a very interesting video coverage of not only the antennas but the entire site. ESPECIALLY want to thank you for pointing out the book _Titan II Handbook_. It will be added to my library soon. My first job in electronics was for "Rockwell International Collins Radio Group" in Richardson, Tx, the first year after RI purchased Collins Radio. I was straight out of USAF microwave technician school. As an Air National Guard troop, I came back to my home station 254 Combat Comm in the Dallas area after graduating tech school (1978). It was a long road, and I was a contractor from 1996 until I retired in 04/2020... 42 years of wearing many hats from RF tech to Sr Eng Tech to PCB layout to Sig Integ Eng to Sr EE when I retired. It was mostly in aerospace and military engineering & engineering support. I worked in different capacities for Rockwell Collins 4 different times, 4 times for Ball Aerospace, General Dynamics, MIT Lincoln Laboratory (one of our national labs),TI, Raytheon, etc. A contractor gets around. It was (mostly) a fun and interesting ride. Best regards, KE5VOC Michael

Cool antenna. From the sweeps it definitely looks like it could use a tear down and cleaning of all the connections, but considering is has been up that long with no maintenance it looks really good. What a cool antenna, thanks so much for sharing it with us.

Thank you for the interesting video. The principle of the antenna was very common for goverment use. Our clubstation have a little version of those system used on the CIA Headquarter in Nürnberg, Germany. They put it to a junkyard, when they leave the areas and we buyed it in the late 90's. Still a nice system👍🏻

We had one on the bow of my first ship (Collins HF discone antenna), the USS Newport News CA-148.

[@titanmissilemuseum]

The book is available only at the museum, or from Amazon or Chuck's website. It's unfortunate that international shipping is so costly.

[@JxH]

@@titanmissilemuseum FYI - I've bought endless books from other countries, including plenty from the USA. I've noticed that some sellers in the USA are able to ship books to Canada for postage costs of (for example, says on the sticker) ~US$5 and they're marked as "Printed Matter" or similar. Other sellers (usually individuals) don't seem to know the trick, and I've bought books for Cdn$38 that cost the poor seller US$40 to ship to me (I felt bad). I do not know the details of this USA postage category trick, but I can tell you that almost all books I've bought from sellers in the USA are shipped for quite low postage costs (not even close to $10). Same thing from the UK too, postage of only a few UK pounds.

@@JxH Within the US, there is an inexpensive shipping option called "media mail" (formerly called "book rate") specifically for books and other media. Unfortunately, this rate is not available for international shipping.

I had some extremely good times building various discone antenna's, the real versions right out of the ARRL The one you diagram is very interesting because it can be used as a "fat" vertical ! Antenna manual. I kick myself now as we had a HF Coast Guard station with a quite unusual antenna (Humboldt Bay) and I haven't been able to find anything showing where they documented that design. I believe it was vertical but I'm not sure. I also believe it was broad banded. We now work with the KFS system which generally uses Log Periodic s The have either re-commisioned some of the old antenna's or added them somehow, and have not only the web sdr system, but the kiwi system for their antennas. I use the SE one, its amazing !

[@californiakayaker]

The "marine" versions required a ton of maintenance. Its crazy but the people who did that do not seem to get on the web much ? I suppose I could write the commander of that coast guard station and see if he has any young guys who aren't partying 24/7 and would have time to took at some of the old documents for diagrams ! lol (But, you had to be around this coast guard bunch to see what I'm talking about).

[@JxH]

The huge metal hoop in the cone presumably isn't required electrically, since the RF voltage all around the hoop would be the same (including phase) due to symmetry, so the huge hoop must be purely structural (a more battle-resistant design). Therefore Amateur versions of this design could presumably use non-conductive ropes to continue the tension path for each cone wire straight down to a circle of stakes in the ground, with the cone wires taking the bend towards the base (I trust that most people can easily follow what I saying here). If anyone wishes to include the hoop (electrically), then horizontal connections could be added from each cone wire bend point to the adjacent ones. Height-wise, 22m isn't all that tall, plenty of hams have towers that tall, so reproducing an electrically-equivalent version of this design isn't all that far fetched. I'm not sure it's worth the effort, but it should be do-able for those interested.

[@rogergrimsby5805]

> i'm not sure it's worth the effort Some people just need to modify their transceivers so they'll transmit out of band; not sure why. "There might be an emergency..." But, they'll be needing an all-band antenna, hi.

They typically bury one 1/4 wave radial every 3° - for about 120, 66' radials or 1.5 MILES of ground radials.

[@tpcdude]

We need a kit of parts with dimensions to build new ones .. perhaps not nuc blast hardened. how big is the screen for example?

[@loughkb]

You should have all the info you need to figure it out. I paused on the page of the book with all of the dimensions, on purpose. I also gave the basic discone dimensions related to frequency and the ratio of disc to cone wire lengths in the graphics. If someone has the room and the time, they can build one.

[@tpcdude]

I wonder if they had access to both feedpoints to set it up for either mode. I have been to This museum .. you want to have a friend take a picture of you scaling the chain link fence near the sign that says "deadly force authorized"

[@loughkb]

Chuck talked about that during the interview. The feed points.
