UHF aerial

BW,
27Mhz is for AM CBs only, UHF CBs use 476 /477Mhz. In short, no it will not work effectively & could damage your radio !

Mark.

Yes I agree with the first reply. The two radios are completely different frequecies. 27meg is in the HF range and the other is miles away in the UHF range. 27meg radio waves are 11 metres in size and the most common aerials are one quarter of that either as a straight piece if stainless steel a bit over 2 metres long or the same length in copper wound around a fibreglass stick. The equivalent aerial for UHF is much much shorter. Back to the seller tomorrow I suggest!

that should be 1100 cm for 27 Mhz (or 11000 mm) - oh well - it's friday :)
