Antenna pictures

[Funksammler]

Thought I'd post some pictures of my KM 8 with Sternantenne after some fun in the garden. This demonstrates the setup sequence of this antenna.

First picture shows the antenna down with the Sternantenne folded ready to go:

Check that the antenna is vertical using the spirit level:

Up she goes! Note the insulator between the mast and Sternantenne and the release rope looped through the black insulator:

Antenna extended still with closed Sternantenne:

One pull on the release line and the Sternantenne opens, the remaining line is the actual antenna feed line connected to the transmitter:

Antenna with opened Sternantenne:

Bottom of the antenna; note the special antenna base for the the Kurbelmast when placed on ground and the two opened steps used when the antenna was mounted on the vehicle:

Ah, so that's what mine should look like...

Very nice. I have 2 of the Sternantenne - I should be able to make 1 serviceable example from them both.

How does the release mechanism work?

Absolutely beautiful!!!!

i love it

How does the release mechanism work?

SpookyDad

There is a spring loaded sleeve with two collars connected to it which can move up and down. The radial rods of the antenna have small hooks which hook behind the lower collar when in the storage position. The spring in the collar keeps them locked in place by pushing the sleeve and collars up. Just under the upper collar the rods have wedges welded to them. When the sleeve with the two collars is pulled down, firstly the hooks are released from the lower collar while the upper collar pushes the antenna rods out via the wedges for an inch or so. Gravity takes over and the rods pivot outwards untill fully opened.

Well, I hope that makes sense!

Where the sleeve fits around the stem of the antenna is usually a corrosion point, on a lot of Sternantennas this section is firmly rusted together and very difficult to free up. So if you buy a Sternantenne, it is worth checking if the unlocking mechanism has movement. If not best to walk away and look for another one!

So the release wire is attached to the sleeve that holds the rods locked and the antenna wire is attached to the short rod that folds down. Correct? Is that a separate wire from the one that pulls the release?

SpookyDad

[Funksammler]

Correct. The release wire was just looped through the insulator that pulled the sleeve down. Once the antenna had unfolded, the release wire was pulled out. The actual antenna wire attached to the big wing on the base of the antenna and suspended away from the mast by the short rod.

Please draw a picture?

At last a question I can answer with some authority. The first picture shows the parts labeled. The antenna is in the closed position. The second picture show the antenna closed and open.

Well done!

Stabhochantenne

I thought time for another antenna! This time I set up the "Stabhochantenne". This is the UHF antenna used with the 20 W.S. b/c/d1 and Ukw.E.b/c/d sets. It consists of a 1.4 m rod with four counterpoise wires, placed on a 5 m Steckmast.

The first picture shows the antenna insulator; the bottom part contains a mounting for the connection box and the counterpoise wires, the top part holds the 1.4 m rod. The two parts are connected by a standard antenna clamp:

The next picture shows a close-up of the connection box. The 7 meter long 2 core feed wire to the transmitter is terminated in the box. The mass wire connects to the counterpoise connection sleeve on the bottom part of the insulator, the wire coming out of the top connects to the 1.4 m rod:

The assembly set up in the clear blue Normandy sky:

This slightly wider angled picture shows the insulator chains between the end of the 1.4 meter long counterpoise wires and the guyropes:

Finally a closeup of one of the insulator chains (Eierkette):
