It is said to have a gain of 2x (times two) or doubling.

two candles) in some directions (but not all directions).

Thus, an antenna with a gain of 3 dBd would have a gain of 5.15 dBi (3 dB + 2.15 dB) 10log (1.64) 2. Antenna gain relative to a dipole antenna can be expressed in decibels as dBd.

Place base plate,grovesfacingupwardsona leveledsurface. (DIAGRAMBELOW SHOWSALL THE COMPONENTSTO A COMPLETE OE-254) 2. Before raising the antenna,inspect all piecesof equipmentinthe antenna kit. Thus a mirror can redirect half of the energy from a candle, and make it look twice as bright (i.e. A dipole antenna gain is 1.64 A half-wave dipole antenna has a power gain of 1.64 (or 2.15 dB) over an isotropic source. OE-254 Cut Sheet NOTES: Make sure the area you choose is clear with a visible line ofsight. The antenna consists of three upward and three downward extended radials. The amount of intensification in a preferred direction is quantified as gain. Antenna Group OE-254/GRC is used to extend the range of the old and new generation of FM field radio sets. Please remember, no new energy is created, it is simply redirected or given directivity. This is directional feature is called GAIN. Antennas don’t create radio energy, they also only divert, direct, or concentrate it in some direction.

Mirrors don’t create light, they only divert, direct, or concentrate it in some direction. Mirrors or lenses have the appearance of intensifying energy in some preferred directions by stealing and redirecting energy from disadvantaged directions.Īntennas do the same thing.

The other half of the room would be TWICE as bright, because you can see the real candle PLUS it’s reflection. With a mirror, one half of the room would be dark (behind the mirror). Visualize how it would change the light energy distribution, and give the candle directivity.
