Series: D D VHF/UHF. The D is an olive drab UHF/VHF/UHF dual frequency air traffic control MULDIPOL™ omni-directional military antenna for ground-air-ground, air traffic control and base communications applications. The VHF input/output operates in the to MHz frequency band and both UHF between MHz. S UHF Satellite Communication antenna provides three functions from single low-profile antenna footprint. The traditional low-angle, vertically-polarized blade can be used for air-to-air and air-to-ground communications. The high .

The AV is a general aviation antenna designed specifically for mounting to the underside of an aircraft, providing an excellent radiation pattern for air-to-ground communications. It has a 4-bolt mounting base and is low in profile. The antenna is designed to operate at speeds up to mph and altitudes up to 50, ft.

The Harry Diamond Laboratories (HDL) has undertaken the investigation of improved communication antennas for the Federal Aviation Administration (FAA). These antennas are used in VHF ( MHz) and UHF ( MHz) frequency spectrums in air/ground air traffic control : A Sindoris, F Farrar, D Schaubert.
The Harry Diamond Laboratories (HDL) undertook the investigation of improved communication antennas for the Federal Aviation Administration (FAA). HDL devoted an intensive design search into available technology, and conducted a concurrent analysis of the key variables affecting the performance of FAA antennas during the first six months of this effort.
Design of VHF and UHF communications air/ground antennas - NASA/ADS The performance of the candidate antennas in a simulated operational environment is calculated and presented for several sets of conditions which closely resemble operational applications. This book contains everything you need to understand how radio signals propagate, how antennas work, and how to construct your own antenna system.
Use The ARRL Antenna Book to build hundreds of antenna designs: dipoles, verticals, loops, beams, and more. The ARRL Antenna Book for Radio Communications is a single resource covering antenna theory, design and construction, and practical treatments and projects. This book contains everything you need to understand how radio signals propagate, how antennas work, and how to construct your own antenna system.
THE (VHF) DIPOLE ANTENNA. At VHF and UHF, most antenna systems are derived from the dipole or its complement, the slot antenna. Many antennas are based on half-wave dipoles fabricated from wire or tubing.
Antenna Products’ discone aviation antennas are designed for ground-to-air communications covering the VHF and UHF frequency bands. Made of corrosion resistant lightweight aluminum, these antennas feature long service life with minimal maintenance.
Construction First of all construct the antenna mount. It is made from a 1/8'' thick aluminum plate cut to 2'' x 6''. Drill a hole in the plate big enough for the SO VHF connector to insert into (about 5/8'' or mm).
Drill the hole at the point about 1" away from one end (see Figure 1. 2).File Size: 2MB. More all-new articles for the antenna experimenter and project builder.

Air Antennas is the realisation of a long-held ambition of owner and founder, Tom Morris. A professional background in the antenna industry spanning 15 years and a passionate amateur radio hobbyist over 30 years, Tom is a recognised authority in the field of antenna design.
UHF antennas. UHF antennas are commonly used for transponders and DMEs and are always found on the bottom of the aircraft. They are about four inches long, and the same antenna is often used for both systems because the transponder frequency is in the middle of the DME frequency band.
The ARRL Antenna Book Build one antenna, and you’ll quickly ﬁ nd yourself planning the next. The ARRL Antenna Book for Radio Communications is devoted entirely to that pioneering spirit. In this one book, you will ﬁ nd all of the information you need for complete antenna systems—from planning, to design and construction.

[F Farrar; D Schaubert; H Jones; United States. Federal Aviation Administration. Systems Research and Development Service.; U.S. Army Harry Diamond Laboratories.]. UHF tuning elements and antennas are even smaller than those of VHF and are much easier to mount on supersonic fighter aircraft, making UHF an ideal choice for ground-to-air communications.
Like VHF radios, UHF radios share the advantages of being line of sight and having wide band-width. Modern military forces now prefer the UHF spectrum for.
Cobham Antenna Systems offer a wide range of VHF antennas for multiple airborne applications. Cobham's range of VHF antennas covers a multitude of airborne applications covering helicopter, passenger aircraft up to fast jets. Variations are also available for both commercial and military VHF on: Cobham Aerospace Connectivity, Marlow, UK.
Lastly regarding gain, if you choose a directional antenna with high gain figures, you will usually want to plan for a mounting scheme that allows pointing, or rotating, the antenna. A directional VHF/UHF antenna can help you reach out and tag that distant station, but unless you can readily rotate it you’re very limited in your direction of.
TCI communications, DF and spectrum monitoring antenna products embody years of experience in RF systems design and production techniques. Broadcasters rely on TCI for optimized HF and MF solutions that minimize operating costs.
Ground-air, ship-shore, GMDSS and military communications use TCI antennas tailored for a variety of power ratings.Rohde & Schwarz HF – VHF/UHF – SHF Antennas | Catalog / The R&S®HKA VHF/UHF omnidirectional ATC antenna is designed for ground-to-air ATC communications.
Due to its modular design, any number of antenna configura-tions (up to an overall height of 10 m) can be set up on the mast. The most important system components are the self.VHF and UHF Antenna Systems cable TV operators as “end runs”—pieces at the end of a roll.
The most common CATV cable is 1/2-inch OD Ω Hardline. Matched-line loss for this cable is about dB/feet at MHz and dB/feet at MHz. Less commonly available from CATV companies is the 3/4-inch ΩFile Size: 2MB.
