| Hmm....why do you believe ferrous material could be used to increase the bandwidth of antennas? I can't immediately think of a way. |

I know it is possible but I d'ont know how to do it /:.
I have another question...i work with transmitter receiver that operate between 30MHz-88MHz.this device connect to single antenna.How it's possible to connect one antenna that opereate in this wide range of frequencies?..i know that for every single frequency the antenna length should be change(wavelegth/2) |

There is twice in your last post you say "I know ...."
For instance, "I know that for every single frequency the antenna length should be wavelength/2"
No. Certain antennas have a resonance at one half wavelength, but this doesn't mean they are not antennas away from this single frequency. Not all antennas radiate at a half-wavelength either.
Generally your post is poorly thought through |
