Unreal Media Server is a software streaming server for Windows operating systems, offering rich choice of live and on demand streaming functionality.

File formats include all the types supported by Microsoft DirectX, namely:
AVI, MPEG-1 (VCD), MPEG-2 (SVCD, DVD), MPEG-4, MPA, WMV, WMA, ASF, MP3, QuickTime (version 2 and lower). Other file formats and compression types are supported with additional installation of corresponding codecs, such as Ogg, DivX, XVid, VP6, Apple mp4, AC3, h.264.

Unreal Media Server does not transcode or decode files when streaming; the files are streamed "as is"; the player is able to playback these files if appropriate codecs are installed on player's computer.

Playlist functionality allows automatically playing all the files of server's virtual folder in a loop mode. Files can be unicasted in "on-demand" mode or multicasted in "live" mode.

Supported live media sources include: USB/Firewire digital cameras, IP network cameras, microphones, TV-tuner cards, analog video sources (analog camera or TV) connected to Graphics card, Video Capture card or hardware encoder appliance that supports DirectShow interface. There can be multiple live sources on a single computer. Hardware-encoded content can be streamed "as is" without software transcoding.

Codecs used for live video compression: Microsoft MPEG-4 V2 and WMV. Codecs used for live audio compression: Fraunhofer MPEG Layer-3 (MP3), GSM 6.10 and WMA.

Two streaming delivery modes are supported: Near-Real-Time and Buffered. Conferencing applications requiring low latency can take advantage of 0.2 - 2 seconds latency provided by Near-Real-Time mode, where buffer sizes are minimal and aggressive leaking-flushing bucket algorithms are enforced. When low latency is not required, Buffered mode can be used, allowing servers to buffer media in order to compensate on network jitter and congestions.

Modem, Slow DSL, DSL, T1, T3, LAN and Advanced compression profiles are supported, allowing choosing specific codecs/bitrates to serve audience with specific network connection speeds.

Live content can be recorded based on scheduler or motion detection, independently of streaming.

Proprietary TCP and HTTP(S) Unicast; RTP Multicast transport protocols are used for streaming content from Media Server to players.
Media Server also supports streaming with MMS over HTTP protocol, which allows interoperability with variety of MMS-capable players on Windows, MAC and Linux.

Unreal Streaming Media Player run on Windows PCs and on Handheld Devices running Windows Mobile 5 operating system. Player can be embedded into web page as an ActiveX control for IE browser or as Mozilla plugin for Gecko based browsers such as FireFox and Netscape.
Players capable of playing MMS protocol such as Windows Media Player can play streaming content as well.

Incoming content is not stored on client computer's hard disk and user is not allowed to save media locally, thus author's rights are fully protected.
User authentication and access restrictions enable trusted access to media resources. User logging provides means to track user activity.

Cushcraft 6 meter, 2 meter, 70 cm YAGI Antenna on Front Antenna Port

Cushcraft's newest multiband directional yagi is designed to provide hobbyists who have limited tower or mast space with directional antenna performance on three of the most popular bands.

Since the three antennas were designed to share a common boom, the A627013S solves the often encountered problem of degraded antenna performance due to inadequate spacing when using separates.

History of the Windom Antenna

During the years 1923 to 1925, several single-wire-fed antennas (both horizontal and vertical) were being described in the ARRL's QST magazine. What made these antennas particularly interesting, was the fact that their single-wire feedline, with a characteristic impedance of about 500Ω, could be easily matched to the valve amplifier end-stages of that time.

In October 1929, after some years of research, William L. Everitt (°1900 - †1986) and J. F. Byrne, both of the Ohio State University, published in the prestigious Proceedings of the IRE an exact method to tune the antenna to resonance and to match the single-wire feedline in order to prevent radiation from the latter. John D. Ryder, at that time student of Everitt, carried out many of the antenna measuring, according to an interview he gave in 1972.

However, Loren Windom, W8GZ, was first to reveal the antenna to the greater radio amateur community by elaborately describing the antenna in the September 1929 issue of QST. It was by Windom's name that the antenna got known outside the USA.

So far, the Windom antenna (see figure below) was an off-center-fed resonant dipole with a single-wire feedline of any length-fed against earth and intended to be used on one frequency only. Its main advantages were its single-wire feedline —would not be of any value anymore today because of propensity to cause RFI— and the fact that it could be easily matched to a valve amplifier.

In 1937, VS1AA was first to describe a compromise multiband Windom. The antenna could be employed on 80, 40, 20 and 10m with considerable, though acceptable levels of VSWR. Feeding was still done over a single-wire, matched with a Collins-filter to a valve amplifier.

What became perhaps the most popular multiband Windom design of all, was the German-made Fritzel FD4 antenna, described by the late Dr. Fritz Spillner^[1], DJ2KY, in 1971. It had the same dimensions as the VS1AA multiband Windom antenna, but fitted with a 300Ω balun at its feed point and-fed over coax. Purists would not call this a Windom antenna anymore because of the absence of the single-wire feedline. The term off-center-fed (OCF) dipole is preferred. By the end of the 70's interest in the Windom antenna was again revived, lead by John Nagle's instructive article that appeared in Ham Radio^[2].

Today, many radio amateurs keep on using multiband Windom antennas with more than satisfactory results. It is not without reason that Windom antennas are being employed at the IARU HF World Championships! Nonetheless, the attention for this type of antenna diminished somewhat over the years, especially with younger amateur radio operators. Perhaps many young hams ignore the multiband Windom antenna because of its sheer simplicity (like I did for some time) and may be considering it to be too good to be true. The complexity of feeding the G5RV, the losses in multiband trap antennas and the esotheric marketing of some other questionable antenna designs understandably seem to appeal more.

This article sets out to continue the tradition of the multiband Windom antenna, however by taking a careful look at its design with the latest, though proven, computer modeling techniques.

Legal Information (General Public)

It is not illegal to receive radio transmissions for the public; therefore, it is not illegal for the public to listen to radio transmissions received by a remote base.

Warning! It may be illegal to receive transmissions you are not licensed to. Any other transmission than the following below, in some countries, may be incriminating to receive;

a) licensed broadcasting stations
b) amateur and citizens' band radio transmissions
c) weather and navigation transmissions

Only licensed radio amateurs may obtain transmit privileges on transceivers located in their country. Depending on the laws for the transceivers country, you may be able to TX as a 3rd Party. For example, in the USA an Amateur Radio Licensee may act as a 'control operator' in transmitting for a non-licensed 3rd party; as long as the Amateur Radio Licensee has full control over the transceiver and properly identifies both stations.

As the audio source from the remote base is not a fixed frequency & is controlled by the control operator, the remote base owner is not responsible for any rules or regulations the control operator did not follow for both owner's & operator's specific country, however; the remote base owner has sole responsibility for stopping any illegal transmission emitting from his/her remote base. Remember that it is you, the control operator, who is responsible for your transmissions, tuning and listening on any remote base. The control operator of any remote base must take responsibility of his/her actions.

[ FCC Part 97.213 ]

Telecommand is defined by the FCC as a one-way transmission to initiate, modify or terminate functions of a device at a distance [97.3(a)(43)]. If you are using a radio or wire line link to remotely control a station, this is "telecommand." The rules contain several requirements for remote control and telecommand operation:

1) Provision must be incorporated to limit transmissions to no more than three minutes if the control link fails. If the control link fails while your transmitter is keyed, the transmitter could be seriously damaged (not to mention the interference it would cause) if there was no three-minute timer to shut if off [97.213(b)]. But this also means that if the control link is functioning properly, there is no requirement for the station to have a three-minute "reset" or turn-off timer.

2) The station must be protected so that unauthorized transmissions cannot be made, whether deliberately or accidentally. This refers to providing safeguards on your remotely controlled station so it cannot be used by unauthorized operators. Most remote station licensees incorporate the use of DTMF tones or CTCSS systems to limit access to the control system to only those people who know the codes. You, as the licensee, are responsible for all transmissions from your remote station, just as you are responsible for your home station [97.213(c)]. This responsibility applies all the time, even if you share the control operator duties with other amateurs.

3) A photocopy of the station license and a label with the name, address, and telephone number of the station licensee and at least one designated control operator must be posted in a conspicuous place at the station location [97.213(d)].

4) Control (or telecommand) links may be wire (a telephone, fiber optic line, Internet, etc.) or radio. The FCC says that if a radio link is used, the station where the control commands are performed is an auxiliary station [97.213(a)] and an auxiliary station is "an amateur station transmitting communications point-to-point within a system of cooperating amateur stations" [97.3(a)(7)]. All auxiliary operations must be conducted on appropriate frequencies above 222.15 MHz.
