Hello,
Bought a Moonraker GAP-F 5/8 wave antenna for 27 MHz.
The antenna is attached to a mast ca. 6 m. above ground and there is nothing around it at least 20m. The cable/connectors are ok and about 10m RG58. The radio is a TTI 1100 4W AM / FM.
After assembly to 6.4 - 6.5 m length I got a scary SWR on 3.5 to 4 ... tried to go back and forth with the last bit but nothing helped. After many attempts, I found that a length of 5.4 - 5.5m helps a lot. On the whole CB band I got a SWR max. 1.4.
The only idea I can come up with is that the antenna is a 1/2 wave not 5/8, or ...?
What's wrong here ?
Thanks in advance,
Daniel
