Antennas should be … The antenna may be offset from the runway centerline and so the final approach course and the runway bearing should be referenced on the IAP chart. Normally not more than 3° however if the approach is continued beyond the runway threshold you will be in a bad position to land Though horizontal dipoles are relatively easy to make, they often take some effort to install in trees or on poles and towers. Height also matters—the higher the dipole, the better. Ideally, a dipole should be at a half wavelength above ground for best performance and making DX contacts. At … In aviation, the instrument landing system (ILS) is a radio navigation system that provides short-range guidance to aircraft to allow them to approach a runway at night or in bad weather. In its original form, it allows an aircraft to approach until it is 200 feet (61 m) over the ground, within a 1 ⁄ 2 mile of the runway. At that point the runway should be visible to the pilot; if it is not I'd say I can reliably get about 50% of the local stations, and then only if the antenna is perfectly aligned.

15 times the diameter of the cable. 20 times the diameter of the cable. When installing a DME antenna, it should be aligned with the VOR antenna. chord line.
A Kabo Air Boeing 747-200, registration 5N-JRM performing Hajj flight NR-1245 from Kano to Sokoto (Nigeria) and further on to Jeddah (Saudi Arabia) with 494 passengers and 18 crew, was cleared to land on Sokoto's runway 08 but landed on opposite runway 26 at about 21:00L (20:00Z).

You can check a few things to see if your antenna could be positioned or aligned better Make sure the antennas are aligned to center of the signal path and angle, and on the same level plane. Tip 3 - Know Your Overall System Gain Required to Meet the Distance The more the distance between the radios, the more the overall system gain needs to be. Antennas for the Beginner Every ham knows how to make and install wire antennas. But if you've never done it, you probably have a few questions.

B) No set minimum as long as the equipment receives adequate cooling and damage protection. C) 3 inches with the seat unoccupied. A) indicate the distance the airplane is from the end of the runway. should be aligned within +- 10 degrees of the longitudinal axis horizontally, and at a 45 degree downward angle as shown in Fig 2. 3 When installing the antenna, make sure the base of the antenna is electrically bonded to the tubing frame.
When used in conjunction with an ILS, the DME is often sited midway between the reciprocal runway thresholds with the internal delay modified so that one unit can provide distance information to either runway threshold. The antenna mast is installed vertically in a place where it will receive maximum satellite signals that won’t be obstructed. The antenna is aligned to the north using an adapter with threadlocker to prevent any movement. Practical experiments using this antenna with both an ATC transponder and with a DME (same frequency band) gave excellent results. Thanks to its gain, this antenna can fully meet the ICAO specifications with a transponder output power of only 25W. The antenna gain is not the only advantage of the new transponder antenna. Since the
Avoid installing your antenna underneath tree braches or other overhanging objects.

e. Because the ADF receiver is susceptible to aircraft radiated noise, antenna leadins should be routed so that they are kept away from electric power cables, alternators, solid state power supplies, anticollision lights, pulse transmitting equipment, etc. standard with a 3 dBi Omni antenna and the 2.4 GHz radios come stan-dard with a 2.1 dBi gain Omni antenna. If more gain is necessary, choose a higher gain antenna depending on your system requirement. The table below shows the signal loss across cables and connections.
