Jun 11, 2019. #6. Commercial HF aircraft antennas are built into the tail. In the old days the antenna was an end fed zepp and was towed behind the aircraft after reaching altitude. It was reeled back in to land. The idea that the aircraft body acts as part of a dipole seems unlikely You can get an aircraft antenna tuned for 2m VHF. Also, you can use just about anything for HF with the right antenna tuner. An automatic tuner might work well for aircraft use. 2m works well from the air, no problem with multiple repeaters or flying out of range.. It works much better than a cell phone.

Primarily designed for military airborne applications that employ probe/cap, shunt or wire antennas When we speak about wire antennas, the first and foremost thought that comes to mind is the 1/2λ Dipole antenna.This is indeed a classic antenna that is not only used extensively by HF amateur radio operators but also by the shortwave broadcasters and various HF commercial radio communication stations around the world. Of course, there are a variety of other types of wire antennas not only.
Antennas should never be painted over their original coatings; any paint buildup reduces the efficiency of an antenna. Real estate is very scarce on an aircraft, and sometimes there is very little left for antennas. Every antenna location is a compromise between a solid mounting, shadowing, other antenna interference, ground planes, and. 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 Comant Monopole DME/ Transponder (TPX) Antenna.

The HF antennas used on the older aircraft consisted simply of an insulated copper wire extended from the fuselage utilizing an electric motor that adjusted the resonant length of the antenna to match the frequency transmitted or received. The HF system on an aircraft provides two-way voice communication with or digitally coded signals for. In aviation we used to note our frequency as Upper or Lower to differentiate between the two. You would say, transmitting 8060 upper, for example. All aircraft HF communication, outside of the military, seems to have gravitated to the upper sideband so we no longer need to say it. (It is assumed. The long wire antenna is an HF antenna, and operates in the 2 to 30 Mhz band. Not all aircraft will use them, only aircraft that need to communicate further than a VHF radio. Typically these are found on larger aircraft including some larger helicopters. The Sea King helicopter uses this antenna as well HF Antennas.

Additional investigations are presented on a low profile wire antenna located on the aircraft tail at close proximity to the aircraft skin Knowledge of antenna installation and maintenance is especially important. Antennas must be electrically matched to the receiver and transmitter which they serve. The following procedures describe the installation of a typical rigid antenna. An incorrect antenna installation could cause equipment failure. The critical length of transmission lines provides minimal attenuation of the transmitted. The HF system consists of: The HF receiver-transmitter The HF control unit The antenna coupler system The antenna The receiver-transmitter operates at high frequencies between 2.0 and 29.999 MHz in one of several different modes. AV2220 - Aircraft Communication Systems Chapter 2 6. 7 On modern aircraft the OMNI antenna is small and belly-mounted, and this could well be the item you saw. HF antennas for the smaller WWII planes, such as fighters, were usually trailing wire, obviously end fed. For larger planes, while many used trailing wires, some used doublets, fed with a tuner, stretched from wing tip to wing tip, fed at.
Most aircraft VHF communications antennas are Marconi antennas. They are vertically polarized and create a field that is omnidirectional.

Above: The Mark 1, Mod 0 Carbon-based, all terrain, night vision capable, 4X4, autonomous, high-altitude HF Wire antenna installation system. I have the highest HF antennas in the neighborhood. I have found that almost any piece or wire or metal will work as an effective antenna on HF if it is long enough and reasonably in the clear optimum performance from your aircraft antenna with very little effort. In this guide we try to demystify and explain items and concepts such as coax cables, types of antennas, the SWR or VSWR reading, best location, grounding of the antenna, ground planes and much more. After reading this document you certainly won't be an expert but you shoul B-29 Corner Perhaps as well known as the command sets is the famous AN/ART-13 and BC-348 combination used in the B-29. That combination forms the central focus of this particular corner of the flight deck out in the radio shack. Recent photos of an actual documented installation in a B-29 are shown at the radio operator's station at Enola Gay crew positions, though it should be noted that. The loop antenna is a flat antenna usually located on the bottom of theaircraft, while the sense antenna is a long wire that often runs from top of the tail tothe top of the of the cabin. (On larger aircraft, the sense antenna may be located on thebottom of the aircraft.) More recent ADFs have a combined loop/sense antenna
The Pilot's Handbook for these aircraft advised the pilot to extend the antenna during flight only when actually using the function, since it causes a certain definite, though small, loss in maximum speed (1 mph). Removal of the much larger forward antenna mast may have led to a significant increase in maximum speed The paints used by antenna manufacturers back then and now are either epoxy or polyurethane. I have heard that some airlines have in there MPM the procedure for painting antenna's and I have also found on the net a Navy document NA 01-1A-22 that is titled Aircraft Radomes and Antenna Covers that has procedured for painting antenna's VHF & UHF Antennas Antenna Products manufactures a broad line of VHF and UHF military antennas including manpacks, shipboard units, surveillance, vehicle-mounted designs and one of the industry's most comprehensive lines of ground-to-air collinear omni-directional dipole antennas.

On most (if not all) aircraft, ATC antennas are generally referred to as the system sending Mode A/C or ADS-B information to Air Traffic Control centers. There is no voice communication on ATC antennas. VHF or HF Comm antenna's are used for voice communications. VHF Comm antennas are usually around 14-18 inches in length and seem to be well. 135 family of aircraft. The Integral Dorsal HF Notch Antenna replaces the existing Dorsal Fin with a composite Dorsal Fin with the HF Antenna mounted internally. Our HF Dorsal Fin Notch Antenna program will take your existing HF system into the 21st century by improving HF receive and transmit and by meeting the requirements for HF Datalink Conformal shunt and loop antennas, like the HF antenna modeled on the vertical stabilizer of the demonstration aircraft, reduce drag, allowing for fuel savings and subsequently lower operating costs. For antennas in the HF frequency range (2 MHz to 30 MHz), the aircraft itself is part of the radiator Aircraft maintenance depots and main operating bases need to be able to perform quick checks of the electromagnetic pulse (EMP) hardness of their systems without removing them from service for any length of time. Preliminary tests have shown that the onboard HF antennas of the EMP Test-Bed Aircraft (EMPTAC) may be capable of providing the HF excitation required to effectively monitor the EMP.
Broden also explained that the HF-9500 system also offers the option of the lightweight and flexible HF-9545 antenna coupler which can be used with any configuration of aircraft antenna. HF Modernization . HF is making a comeback as threats against SATCOM become more prevalent. The Department of Defense plans to phase in full HF Modernization. An objective of the shunt antenna is providing an antenna that can be retrofitted to existing Boeing aircraft in a location other than the vertical stabilizer of the aircraft, but transmitting an equal or better signal and receiving a weaker signal than existing HF antennas
