my old 16 foot shakespear super bigstick had a low power matching circuit inside made of a capaciter and a small coil. when i blew it up with 300w from a skipper300 i disected it and saw the burned components.
they do ok at lower power unless there was a different version that used a higher power matching circuit. maybe the one with the pigtail. mine didnt have the pigtail.
I'm not sure NB, but I think you have it wrong, but I'm open to a better understanding on the S/P Big Stick. S/P made several base antennas for CB over time.
They made the Super Big Stick-NBS 2010, 3pc and probably had a tuner inside like you describe. 1/2 or 5/8 I not sure
They made the ABS 1600, Army Big Stick, 3 pc, 21' long and probably had a tuner like you describe, for sure a 5/8 wave as advertised.
They made the UPS Super Big Stick, 2pc, 16' long that I think was a sleeved dipole inside. I think this is what I first had.
They made the BS, 2pc, 18.5' foot I think, and I think it too was a sleeved dipole inside. I had this years later, and may be what 351 has.
They also made a Big StickII that was 2pc, and had a pigtail attached, which someone else has talked about here or in another thread. I was wrong about this one though, I called it a Marine Big Stick, which I think that one was one pc, 1/4 wave with a pigtail.
the model of this anttena is 176-s its 2 sections the bottom section looks about 12 foot and the top section is about 8 feet
if this isnt a decent anttena i will sell it
351 describes his antenna as two piece and figures it's 20' feet long. I'm not sure about the length, but that could be about right. However there is a difference between the S/P Super Big Stick, and the S/P BS that I think 351 talks about in his original post.
Freecell said the following, and this is
the way I visualize the S/P BS in my mind, being a center fed sleeved dipole...whereas FC calls it a coaxial 1/2 wave dipole.
I know nothing about FC's final remarks however.
the shakespeare big stick # 176 (if that's the model you have) is a coaxial halfwave dipole with less bandwidth, less gain, (if we pretend that the A99 is just an end fed half wave vertical) handles a fraction of the power of the A99 with no where near the wind survival rating. it's so pathetic as a matter of fact that now it's called the 176-1 and is marketed as a marine cb antenna. both manufacturers also lied in equal amounts when it came to the advertised gain ratings.
i hear they make great fishing rods.
I also recall doing a continuity test on the BS and it was an open circuit, and the matcher you describe sounds like what is inside the S/P Super Big Stick and the maybe the NBS. All 351 has to do is check the continuity on his and tell us if it is and open or closed circuit, both the SBS and the NBS should show a closed circuit. This should give us a clue what the matching inside might be, a center fed sleeved dipole or a coil with a capacitor.
