Military radio antenna kites past and present

Military radio antenna kites have a long and fascinating history. They've been used to transmit vital information during times of war and conflict.

In World War I, kites were first used to lift radio antennas high above the battlefield. This allowed soldiers to communicate with each other over long distances.

The use of kites in military radio communication continued through World War II, where they played a crucial role in coordinating air support and ground operations.

These early kites were often made of lightweight materials like silk or paper, and were designed to be easy to assemble and transport.

Military radio antenna kites have a rich history that spans over a century. The first recorded use of kites for radio communication was in 1898 by Greenleaf Whittier Pickard, who used a small box kite to raise a wire half a mile up for wireless tests at the Blue Hill Meteorological Observatory in Milton, Massachusetts.

One of the earliest notable uses of kites for radio communication was by Guglielmo Marconi, who sent the first transatlantic radio signal in 1901 using a Baden-Powell Levitor kite to raise the antenna.

The United States Signal Corps maintained three models of antenna lifting kites as standard equipment, listed in the Signal Corps Storage Catalogue as late as 1920. These kites, known as KI-1, KI-2, and KI-3, were used with portable field wireless sets and were designed to be compact and lightweight.

In 1922, the United States Navy experimented with kites for emergency radio use, designing kites to lift antenna for radios in downed seaplanes. Two kites were issued, one for stronger and the other for lighter winds, as well as a reel of light antenna wire and a small generator.

The German military issued the NSG2 emergency radio for use in lifeboats in 1941, which included a winged box kite to raise the antenna. The British captured an NSG2 and copied it as the "Dinghy Transmitter" T-1333, using a box kite with the set until 1943 when they switched to a kite similar to Silas J. Conyne's 1911 design.

The United States Army Air Forces used a similar kite, the M-277-A, to raise the antenna for the SCR-578 survival radio during World War II. The kite was collapsible and could fly in winds from 7 to 40 miles per hour. It was designed to be simple to assemble and could be stored in a cardboard tube.

The British Royal Navy experimented with kite raising antennae on HMS Good Hope in 1903, using a box kite designed by Samuel Franklin Cody. A 300-foot kite raised antenna increased their radio range from 60 or 70 miles to 110 miles.

Here are some notable military radio antenna kites:

Military radio antenna kites were used in various forms throughout history. The United States Signal Corps maintained three models of antenna lifting kites as standard equipment, listed in their Signal Corps Storage Catalogue as late as 1920.

The KI-1, KI-2, and KI-3 kites were designed for use with portable field wireless sets. Kite KI-1 was made of spruce rods, cloth, and wire, measuring 60 by 60 inches. Kite KI-2 was smaller, measuring 6 feet high by 6 feet wide, while KI-3 was 7 1/2 by 7 1/2.

Here are the key differences between the KI-2 and KI-3 kites:

The KI-2 and KI-3 kites were intended for use with the SCR-44 field wireless set, a pre-World War I pack set.

The Ki kites were a crucial part of early military radio communication systems. They were used to lift antennas for radios in downed seaplanes.

The United States Signal Corps maintained three standard models of antenna lifting kites, listed in the Signal Corps Storage Catalogue as late as 1920. These kites were used with portable field wireless sets.

Kite KI-1, formerly known as the "folding Malay kite", was made of spruce rods and measured 60 by 60 inches. It was used with portable field wireless sets.

The Signal Corps also had two other kite models, KI-2 and KI-3, which were used with the SCR-44 field wireless set. KI-2 was smaller, measuring 6 feet high by 6 feet wide, while KI-3 was 7 1/2 by 7 1/2 feet.

The United States Navy experimented with kites for emergency radio use as early as 1922. Commander Taylor and Lieutenant C. D. Palmer designed kites to lift antennas for radios in downed seaplanes.

The Navy issued two kites, one for stronger winds and the other for lighter winds, along with a reel of light antenna wire and a small generator. This equipment was used to power the radio in emergency situations.

Here are the specifications of the three Signal Corps kite models:

The Kites M 277 are an interesting aspect of military radio antenna kites. They were used to raise the antenna for the SCR-578 survival radio in World War II.

These kites were collapsible and made of aluminum rods, with a frame that could be opened up like an umbrella. They were designed to be simple to assemble and could fly in winds from 7 to 40 miles per hour.

The M-277-A kite had a 17 x 17 x 36 inch frame and was made up of 4 aluminum rods, each rod end attached at the ends by a hinge to 4 shorter rods. It was treated with water repellent and had a yellow cloth section filled with kapok to add buoyancy if it fell into the water.

The kite packed into a cardboard tube, on which were also printed the assembly instructions. It had two bridle attachment points, one for winds 7–20 miles per hour, and the other for 15–40 miles per hour.

Here are the key specifications of the M-277-A and M-357-A kites:

The M-357-A is identical to the M-277-A except that the frame can be separated into two pieces, making it easier to store.

The British Royal Navy experimented with kite raising antennae on HMS Good Hope in 1903, using a box kite designed by Samuel Franklin Cody, increasing their radio range from 60 or 70 miles to 110 miles.

In 1911, the United States Navy conducted kite antenna experiments on the torpedo boats USS Stringham and USS Bailey.

Some Signal Corps units conducted kite antenna experiments independently, often constructing their own kites. The First Company, Signal Corps, National Guard of New York, made box, Malay and hexagon shaped kites in June 1907 to experiment with raising standard international code flag signals and radio antennae.

Charles H. Cole, Adjutant General of Massachusetts, experimented with kite supported antennae in 1915 after hearing about the German ship Prinz Eitel Friedrich's success using kites to suspend a radio antenna.

Perkins' original kite configuration swayed up and down considerably, causing the antenna to vary in length and making tuning difficult. This problem had been a challenge since kites were used for raising antennae, and had almost led to their abandonment.

The tests conducted by Cole and Perkins were considered a success, with messages sent using a field wireless set with the kite antenna being heard 150 miles away, where the same set could normally transmit only 25 miles.

The Bendix M-357-A Antenna Kite is a rare and historic example of a military radio antenna kite. It's currently on display at the Fort Miles Museum in the Battery 519 Gallery.

Manufactured by the Bendix Aviation Corporation from 1941 to the end of WWII, these kites were used to hoist the antenna for the SCR-578 survival radio. The kite was used in conjunction with multi-man life rafts during World War II.

A 260-foot antenna cable was attached to the kite, which was then tossed into the air. The kite has been donated by Fred Noll, a longtime member of the Fort Miles Historical Association.

Military radio antenna kites are designed to fly high, often above 10,000 feet, to reach distant communication targets. This allows for long-range communication between units.

The use of kites in military communication dates back to World War I, where they were used to relay messages. Kites have since been adapted for various military applications.

Kites can be equipped with advanced antenna systems, such as directional antennas, to improve communication quality. This is particularly useful in areas with high levels of interference.

The high altitude of kites also helps to reduce signal interference from the ground, allowing for clearer communication. This is especially important in areas with heavy population density.

Kites can be controlled remotely, allowing for precise placement and retrieval. This is achieved through the use of GPS and other navigation systems.

The use of kites in military communication has also led to the development of specialized equipment, such as kite launchers and retrieval systems. These systems make it easier to deploy and recover kites in the field.
