i know often it is said height is might, but is there such a thing as being between wave lenghts. i understand 36' is the first wave length. what is the next would it be 72' and if you were in between would it harm your signal out put with ground waveing.can you actualy be out of wave length with antenna height.can you be too heigh and what are the actual wave lenght heights. |

DEPENDS ..... If you on say 440 mhz you only have to be 24 inches ( one wavelengh ) up and your at a good height. HOWEVER if you get a mile you'll be doing good. Now raise that antenna to 2400 foot and you'll talk 100 miles. Same on CB only a good height would be about 35 foot ( again one wave ) ..... and anything above that is going to increase range .... On 6 since 66

Don`t muddy up your brain worrying about wavelenghts. You can never be too high. Put it up as high as you can for maximum range. |

The higher the antenna the lower the radiation angle lower angle means better skip condx,so an antenna 72 feet high will work better for long skip such as Europe, lower height will often work better for short skip such as E skip which is usually of a higher angle of radiation.The bottom line is make the best with what you have and hope for better Bob CEF451/VE1CZ Robert L.

I'm no antenna expert but this was said to me years ago and is so basic it's ridiculous. HEIGHT IS MIGHT By getting your antenna up as high as you can you move the horizon further away. Therefore you should be able to cover a greater area. The laws of physics are NOT written in stone. Sometimes things work that defy the laws...enjoy it if it does.

Anyone know of an antenna that gets out better than the antron 99 and has more gain? excluding beams |

Mtn_man_754, The A-99 is a 1/2 wave over 1/4 wave antenna, the MACO 5/8 and V-5000 are 5/8 wave antennas and the IMAX 2000 is a .64 wave antenna. For more information CLICK HERE >Imax 2000 Exposed by: Tech833 And for even more information go here: Copper Talk » Subscriber (Preview) » Product Reviews » Imax 2000 Exposed Base Antenna » Discussion Hope this help's,

Lon, the A99 is a 1/2 wave and the Maco V58, V5000 and the Imax are all 5/8 wave ants. Move along. Nothing to see here.........

Train_man, My mistake for typing too fast yesterday, the Solarcon / Antron 99 is a 1/2 wave over 1/4 wave antenna. The MACO V-5/8 and MACO V-5000 are 5/8 wave antennas. The Solorcon IMAX 2000 advertised as a 5/8 wave antenna is actually a .64 wave antenna. I corrected my post above from yesterday also.

Copper's and Maco both indicate that the V 5/8 is a 5/8 wave high gain antenna. Even the model name gives us a clue as to the manufacturer's claim. |
