Funksammler Posted March 6, 2019 Author Share Posted March 6, 2019 By the way, there is also a thread on the "Festungs Funkgeräteschrank". Apparently there were a large type (Type 1) and a smaller type (Type 2): https://forum.axishistory.com/viewtopic.php?f=70&t=183242 regards, Funksammler 1 Link to comment Share on other sites More sharing options...

tornfuté Posted March 6, 2019 Share Posted March 6, 2019 It become more easy to understand thanks FS for picture. i have readen again D1790/1 , 5, 6, i have seen inside those notices that there Is also D1790/2 and D1790/4 has anybody knowledge of D1790/3? i can buy one time copy of D1790/2 but 100€ for copies too expensive we are always speaking about the emergency antenna put in a well or duct but they are others antenna used and connected to set by other way sometimes they use the N4 with a self made support for antenna or they used side of bunker to connect an antenna . i post here some pictures seen in D1790/6 , where we see an antenna base alter art , so meaning that there is also a n A neu art . the funkschrank illustrated in bunkerforum is what i had said in a previous post but i was’nt aware that 2 different type exist. it stand near niche 4 in entry just near N4 it has sense if set ,antenna, are stowed there Link to comment Share on other sites More sharing options...

val Posted March 14, 2019 Share Posted March 14, 2019 @Lenny - regarding that separate proper download area you mentioned- would there be a file size limit? We currently like to share here ~100MB file, but this exeeds the attachment limit... Link to comment Share on other sites More sharing options...
PE1RNL Posted May 29, 2019 Share Posted May 29, 2019 Hi everyone, I made few pictures of the Verschlußkopf on top of the local Battalions-Gefechtsstand. For displaying the antenna would be nice to have such a part connected to a frame with a clear acrylic tube as Antennenführungsrohr to put the antenna in or maybe even better, make a copy of the Verschlußkopf in plexiglass as well. As we can see in pictures in D-1790-3 This tube is 108 x 3.75 nach Din2448 with a length of 2.3 m. You see the end of this iron Antennenführungsrohr in the Verschlußkopf in the last picture . I never saw a picture in wartime with this antenna, only wire antennas. For HF, wire antennas seem a better option to me also because those can be used with lot more power and low profile and why not use a dipole for VHF? Maybe the 3 whips made it more broadband? Still in the publication "Funker im Bunker!" it says in second line already "Ist eine Festungsantenne eigebaut, dann verwendest Du diese!" What we can see in the placing of the Verschlußköpfe on top of bunkers is that many times 2 are close together and never could not be used at the same time, even for just receiving, because the whips would touch each other. What would be interesting is testing the working of the antenna. I am thinking of trying to make a solid type of the Antennenspreizkopf. What I need to know is the angle of the whips when spread. What I measured in all the drawings that would be around 155° with the vertical axis, so that's about 65° to the horizontal. I hope Funksammler can confirm this. regards, Kees 2 Link to comment Share on other sites More sharing options...
Funksammler Posted May 29, 2019 Author Share Posted May 29, 2019 Thanks for posting some great photographs of the antenna tubes, they are certainly not lacking on this particular bunker! You will have to remind me about measuring the angle in the couple of weeks, at the moment I am moving around part of the collection, suffering from poor access and lack of time at the moment... regards, Funksammler 2 Link to comment Share on other sites More sharing options...
