The antenna is a 23 foot Shakespeare whip. I´ve checked the
connections to it and they appear to be good. I´ve been told that my signal sounds good although I can only transmit at low power. I would have thought that at some frequency that the antenna would be tuned. -- Geoff Freebee wrote in message . .. you didn't say what the antenna is - assuming sailboat backstay - maybe check the condition of the HT wire from the tuner to the backstay?

The electrical length of it is considerably longer than 23'. It'll resonate lower than 10 Mhz somewhere...... |

Only a small part of the antenna would be effective on the higher frequencies. Regards Gary God, that must suck! Base loaded with a crappy, lossy tuner AND a way-too-short antenna with only an E-field with almost no antenna current...... NO wonder they all sound so crappy! |
