I want to assemble my old Long John Five Element with it's 24 ft long boom. Trouble is I haven't got the plans anymore. I contacted Hy-Gain and was told they don't support any of the 11 meter stuff anymore. Can anyone help me with the Dimensions? |

Most antennas will have marks on the parts from when you had it up last ....... since the elements on a simular beam should be close in length see if you can find a 5 elm maco and start with that ........ and if it looks good crank the clamps tight! |

The Maco M105C Antennas boom length is 309"
25ft 9 inches.
I don't know anyone that has the Old
Longjohn assembly directions or where you
could even locate them...Hummm

Bruce,
I e-mailed him the Maco 5 element assembly
directions to try.
I tried locating Longjohn specs, but, just
can't locate them.

Thanks but my boom is only 24 feet long. So I can't really go with 26 foot long Maco. |

Decrease spacing by 6 inches between elements,my gosh, that should get you in the ball park,just remember that a cb antenna is just that,rear rejection will suffer in the higher freqs.(free-band)so keep that in mind.Bigbob |

That small change in boom length should not mean that much as far as the elm length i still think the maco will be close enough. |
