The Heinrich Hertz Tower is an impressive broadcast tower in the center of Hamburg and also the tallest building in the city at 279.2 m (916 ft). The tower is also called 'Telemichel'. In the photo, the tower is colored by sunset.

Shelby machte einen Handel mit Hertz Autovermietung, um eine spezielle Serie von GT350s zur Vermietung herzustellen. Das von Hertz gestartete Programm nannte sich „Rent-A-Racer“. Diese GT350H sind sehr selten und heute sehr gesucht. Shelby fertigte 936 Stück dieser Wagen .. ungefähr 800 in Schwarz .. 😎👍
Shelby made a deal with Hertz Rental Cars to make a special line of GT350s for rental. The program started by Hertz was called "Rent-A-Racer". These GT350H are very rare and much sought after today. Shelby made 936 of these cars.. about 800 in black.. 😎👍

The Heinrich Hertz Tower (German: Heinrich-Hertz-Turm) is a landmark radio telecommunication tower in the city of Hamburg, Germany.
Designed by architect Fritz Trautwein, in co-operation with civil engineers Jörg Schlaich, Rudolf Bergermann and Fritz Leonhardt, the tower was built between 1965–1968 for the former Deutsche Bundespost (German Federal Post and Telecommunications Agency, now Deutsche Telekom's subsidiary Deutsche Funkturm GmbH) near Planten un Blomen park.
With an overall height of 279.2 m (916 ft) it is Hamburg's tallest structure, consisting of a 204 m (670 ft) steel-reinforced concrete lower section topped by a 45 m (148 ft) steel-lattice tower and a three-segmented cylinder of about 30 m (98 ft), which supports various antennas

At one time, customers could actually rent a Shelby GT350 at Hertz Rent a Car facilities. The 'H' signifies the ones that were once part of the Hertz fleet.

Note: I do question the article stating that the engine was a single overhead cam (SOHC) design because it is instead an overhead valve (OHV) design.

The sepia effect from iPhoto, Mac's older photo-manager. I still like it better than Photos, their newer one. The old one has more interesting edits to offer. And Flickr Editor offers the frame. All free (more or less), after you buy the computer and join Flickr!
Thanks for looking :-)
The Heinrich-Hertz-Turm (named after the German physicist and Hamburg-born Heinrich Hertz) is a radio telecommunication tower and a famous landmark of Hamburg, Germany.
Technology image of the week:
These spiky carbon-impregnated foam pyramids, seen here in ESA’s Hertz test chamber, cover the walls of facilities that simulate the endless void of space.
This ‘anechoic’ foam absorbs radio signals, enabling radio-frequency testing without any distorting reflections from the chamber walls. In addition, it also absorbs sound – making these chambers eerily quiet places to work.
ESA’s Hertz chamber, in its technical centre in the Netherlands, is an isolated metal-walled chamber offering versatile ways of measuring a subject’s radio-frequency performance. Its walls block all external electromagnetic energy such as TV broadcasts and mobile phone signals for uninterrupted testing.
Other ESA radio-frequency testing facilities – including the smaller Compact Antenna Test Range and the Maxwell chamber for assessing the electromagnetic compatibility of satellite systems – are similarly clad with foam.

ESA test facilities can test more than just space hardware: here, the 2.0m-diameter nose of an Airbus A340 aircraft is seen in ESA’s Hertz chamber, undergoing radio-frequency testing.
“We had a rare gap in our test schedule and were able to accommodate a commercial customer,” explains ESA antenna engineer Eric Van Der Houwen.
“SPECTO Aerospace works on repairing damaged structural aircraft parts like radomes – radar domes – found on the noses of aircraft, which protect forward-looking weather radar and other equipment. But before any repaired radome can be returned to flight it needs radio frequency testing to confirm the repair has been a success and the structure is performing acceptably.”
A radome can be damaged in various ways, including lightning strikes, bird strikes or due to hail erosion. The repair process needs to return the radome – an aramid fibre honeycomb composite sandwich structure – to be high mechanically stiff and aerodynamically smooth – while also ensuring its desired radio-frequency (RF) performance remains intact.
“Sometimes a repaired radome can look good but might not perform so well in RF terms,” adds Eric. “It might be that the radome structure is absorbing too much RF energy, or triggering signal reflections or interactions that alter the shape of what should be a forward-looking signal. In this particular case, this radome requires a ‘side lobe level test’ – checking its sideways emissions.
“So we first of all measure the antenna pattern and energy level without the radome and then with the radome to see how much these values change. Finally we again test the antenna without the radome, to make sure our results match on a reliable basis.”
Part of ESA’s technical heart in the Netherlands, the metal-walled ‘Hybrid European Radio Frequency and Antenna Test Zone’ chamber is shut off from all external influences. Its internal walls are studded with radio-absorbing ‘anechoic’ foam pyramids, allowing radio-frequency testing without any distorting reflections.
The Hertz chamber carried out a rapid test campaign for the company, with the nose cone – which fits onto both Airbus A330 and A340 aircraft – into and out of ESA’s ESTEC technical centre in Noordwijk, the Netherlands in a single day.
“ESA is one of our reliable partners for specific aircraft parts testing,” remarks Jeroen Mast, managing director of SPECTO. “Our in-house test facility is able to perform the standard transmission efficiency tests for aircraft radomes, with ESA’s anechoic test facilities offering a valuable add-on to our services.”
ESA’s test facilities at the service of all Agency missions and Member States are supported through ESA’s Basic Activities. At the Space19+ Council of Ministers in Seville, Spain on 27-28 November, ESA will press for an increase in Basic Activities to maintain and develop its test facilities and general infrastructure.

A view inside ESA’s cavernous Hertz chamber for radio-frequency testing of satellites, which will be on show to the public during this Sunday’s ESA Open Day in the Netherlands.
Isolated from the outside world with radio- and sound-absorbing internal walls, the chamber simulates the boundless conditions of space.
Its hybrid nature makes it unique: Hertz can assess radio signals from antennas either on a local ‘near-field’ basis or as if the signal has crossed thousands of kilometres of space, allowing it to serve all kinds of satellites and antenna systems.
This photo was taken during a visit to ESA’s technical centre in Noordwijk, the Netherlands by artist and photographer Monica Alcazar-Duarte: “Once the door of the chamber was opened I was presented with a landscape that could have come from a science fiction film. I know this is not the case of course but the room was incredibly inspiring.”
ESA’s Open Day in the Netherlands takes place on Sunday 8 October .
