• Moved from Bard Hill to continue the passive detection work. Subsequently used for a variety of purposes from Quality assurance to the GEC archives. K Block. Built to house the expansion of the microwave work and opened by a government minister. This did not last. Became the home of the Marconi archives until they went to Oxford . L Block
• Normally, the ' WindoVert ' by itself is the antenna of choice. It does make QRP contacts, although any QRP on 160 is a challenge. If you are looking to get on 160 from a small yard, and have a Windom or a dipole that can be converted to a Marconi style antenna, this could be your best bet for a simple antenna.
• Feb 21, 2019 · First solder the reflector on the waveguide, see the picture below. Keep the plate aligned at 90° to the 22mm tube at the right place (e.g. with an olive or clamp ring under-neath), hold the assembly in a vice, taking care not to crush the copper tubing and ensure 9 - 10mm of 22mm tube is protruding above the reflector. Don't use excessive solder.
• MARCONI 'T' ANTENNA CONFIGURATION. Adapting the main HF Doublet Antenna as a type of ‘T’ Antenna was achieved by bonding the ladder line in the shack and connecting directly to the T-Match antenna tuner. Principal of the 'T' Antenna. The Marconi ‘T’ Antenna is essentially a shortened vertically polarized monopole antenna that is used for lower frequency bands, typically below 4 MHz and ideal for use on the 160m (1.8MHz) amateur band.
• The latter was a diode (two electrode) vacuum tube, and was the first truly electronic device to be used at the Marconi stations. Equipment to record incoming signals was added in later years. The Marconi Towers station occupied about five hundred acres of land, the large area being required for the antenna arrays.

Photograph of Guglielmo Marconi and associates raising the receiving antenna by kite at St. John's, Newfoundland in December, 1901 in preparation for his historic first transatlantic radio transmission 11 December 1901 from Poldhu, Cornwall, a distance of 2300 mi (3500 km).
• Instead, they attached an antenna to a balloon, which blew away, and then to a kite on a 500 ft. tether. Kemp and Marconi continued attempting to send messages, but they could not receive them. December 12,1901, using the fourth kite of the experiment, Marconi and Kemp at last heard a signal.
• Marconi Antennas for 160 Meters. I was recently reminded that vertical antennas are also known as Marconi antennas. It's cool to think of the important role that these antennas played in the development of wireless communication. They remain very popular for Amateur Radio use, especially for the 40-160 meter bands.

• Frank Murmann Antennas private aircraft. On any airplane, often on its belly, you’ll find dozens of antennas that are each used for a different purpose. Called aerials by a lot of pilots who have been in the business for a while, these antennas are there mostly to help the pilots communicate with other people, and most of them look like lightning rods or other interesting protrusions.

• Dec 12, 2016 · Later Marconi then placed an antenna and receiving station at the “Twin Lights” Navesink Light Station to demonstrate his Wireless Telegraph. The New York Herald newspaper had hired him to report on the 1899 America’s Cup yacht races which were being held off the tip of Sandy Hook, the first use of wireless telegraphy on a commercial basis.
• He raised the antenna and grounded the transmitter and receiver. Marconi wanted to concentrate the signal into one spot rather than the signal beam being spread out. It made the device capable of receiving and emitting signals to up to two miles in range. Marconi's experiments were successful, and this meant that his invention needed more ...
• By the end of March, 1915, the Marconi Company had 225 coast stations and 1,894 ships equipped with their wireless apparatus.The Aldene plant provided all the apparatus accompanying receivers and transmitters, such as spark gaps, telegraph keys. wavemeters, antenna switches, and Leyden jars.

• This article describes the characteristics of the Marconi antenna and shows the results of several simulations made with MMANA-GAL, covering models optimized for the 20 m, 40 m and 80 m bands. The goal of the simulations is to check the behaviour of the antenna both in it fundamental band of design and in the harmonic bands, taking into account the impedance and the radiation patterns.
• CMC Electronics (CMC) has achieved an international reputation for innovation and excellence in the design and manufacture of electronics products for the military and commercial aviation markets.
• Isotropic antenna (idealized) oRadiates power equally in all directions Dipole antennas oHalf-wave dipole antenna (or Hertz antenna) oQuarter-wave vertical antenna (or Marconi antenna) Parabolic Reflective Antenna oUsed for terrestrial microwave and satellite applications oLarger the diameter, the more tightly directional is the beam
• MARCONI 'L' ANTENNA CONFIGURATION. Adapting the main HF Doublet Antenna as 'L' Antenna is achieved by simple connecting to one side of the ladder line in the shack directly to the T-Match antenna tuner. The main HF antenna is an All Band Doublet fed with ladder line and matched with a T-Match antenna tuner including a 1:4 current balun ...
• The image antenna formed in the ground under a Marconi antenna . This type of antenna, unlike the dipole, is an unbalanced antenna, and should be fed directly with coaxial cable. The shield of the coax is connected to the ground at the base of the antenna and the center lead of the coax is connected to the vertical radiator.
