B antenna for an A radio ???

[jasonmbeamer]

I remember learning about antennas years ago. The concept that the wavelength determines the ultimite length of an antenna. the length can be divided by equal amounts.

Example = a full wavelength antenna for a certin frequency is 8 feet
The antenna can be 8 ft, 4ft, 2ft, 1ft etc....

then could i use "B" antennas for an "A" radio ? since "A" is twice the frequency of "B" 2.4ghz as to 5.8ghz

I realize the dbi would be half of the "B" frequency.

but using a "B" antenna should not be a problem for the radio right ?

2 x 2.4 = 4.8, not 5.8.

All is not lost though, since some 2.4 GHz grids are actually not so bad. We figure a 23 dB 2.4 GHz grid gives about a 16 dB at 5.x GHz. It is not real efficient on the pickup but the reflector focuses so much energy it still does pretty good. We have used this to our advantage when changing systems over. Replace the radio the up then go up on roof, mount a 5 GHz antenna and swap the cables, remove the grid and go home. Minimal downtime.

Just worked the math out in my head, boy im glad i use a calc for everything else, hehehehehehe
