longer antenna for a Cell phone
There are companies selling longer antennas for the v400.
Do these longer antennas really help at 1900 and 850 mhz? Thanks Chip |

If they are made correctly longer antennas will have more gain. If not made correctly they may not have any more gain and may have less. |

It may depend on the antenna. If they are made correctly longer antennas will have more gain. If not made correctly they may not have any more gain and may have less. gain is had by reducing gain in other directions. There is nothing to guarantee that using a gain antenna will cause an improvement; the opposite may happen. Especially if the antenna is tilted. |

This actually begs another question.
How efficient compared to (say) a 1/2 wave dopole is the average cell phone antenna? I'd also like to know the difference between those handsets that have a antenna sticking out better or worse (dB pls) than those that dont. I guess body attenuation wd be a major factor too.

Cell phone is -2 to -10 dB average down from 1/2 wave and the pattern is
very splintered. The antenna resonates with parts inside the case and users arm. Longer antenna is defiantly better, IF it is resonate. If you get aftermarket, it may not be. Has to be designed for that particular cellphone. "Bob Bob" wrote in message ... This actually begs another question.

It also helps if you mount the gadget on a broom-stick and hold it at arm's
length well above your head. But you then need an extension lead for an earphone. You also have to shout loud. ---- Reg. |
