[chirp_users] off topic hardware question
Sorry for the off topic...I just purchased a UV-5X3. How do I identify which antenna is for 220? There are two unlabeled whips, one has a black inner core at the connector,,,the other is white, and I can't read the label.
thanks Thom k3hrn

Thom,
Usually if you look directly at the connector end of the antenna, there would be a ring around the female SMA connector that specified the frequency range.

After digging mine out, they are all labeled as to the frequency range. The ones with the white ring are 220, the ones with the black ring are 144/440.

Dear Jim I had 2 off topic questions for you so i emailed them to you directly. Are you answearing outside the Discussion group? Amnon

What wave length would the other be for? To get the wave length that a frequency falls in, just divide 300 by the frequency. 220 would be 1.36 meters. If the other band that the radio does is 2 meters, you would use the smaller antenna. Glenn

Both antennas are shorter than the wavelength for the VHF band that they are designed operate on. The physical length of the single band 220 antenna and the dual band 144/440 antenna are the same (hence the problem identifying them visually).

On mine the band is indicated on the ring around the SMA femaie connector on the bottom of the antenna.
