Center fed verticals like the Gainmaster are like that. They don't like to be close to an earth. That first wavelength or so in height above an earth makes a night and day difference.

After 27 pages of discussion what is the final verdict? How should I mod' the V 4000 that I plan to buy next month?
Thanks guys.
Thanks guys.
I have one Complete LW-150 antenna & lots of parts of another one that I was given Today.One was in a sealed box but when I opened it there was everything except the instruction sheet.I am glad it was still in the box or I would have had no idea what it was.The 2nd antenna is missing the black plastic pieces & most of the hardware but all of the aluminum is still shiny like a New Dime.I even have the 2nd set of the pieces that make the ring so I have lots of spare parts.Could you post a full size copy of the instructions or maybe convert them to a pdf file so I could print them? I am attempting to print these now.I have searched the web & yours are the 1st I have found but it is to small to read so still not much help.Thanks much & God bless.

6 shooter try this PDF file link below. It won't be of much help but I think this antenna kit was made fixed setup using screws. It does require some tuning however.
Good luck.
I found this link using "WWDX Search" ---- searhing for "Larry 150".

No, my 2000 GTL recap cost a bit more than I predicted it would so I must wait until next month to buy the 4000. No big deal as they're on Amazon for $140 shipped. I just didn't want to find a better setup after I paid for my 4000. The usual.

I just wanted to add a link to my Vector 4K install. It has measurements and a copy of the assembly instructions. Also detailed is the tilt over mast install, if anyone needs more measurements just let me know and I will tip it down and throw a tape on it. I had read this thread when I was trying to decide what antenna to buy and I didn't understand some of it at the time. Now that I an reading back through this, it is more clear to me. This is the best web forum for learning about radios and hope to contribute any way I can.

I almost forgot about the "bird ball" on the top of some Sirio base antennas. I've put this one up and a Sirio 2016. Within a year (depending on your bird population) both had birds land on that ball and jump off in a hurry. As soon as a decent size one jumps off to fly, it will bend the top element. I cut the ball off now and just extend the whip a few inches to compensate for resonance.
All this fancy talk about the 4000 and all I run as a standby is an NOS A/S starduster….
I was told it was a 1/2 wave. 007 has one. Handles big power and get out pretty good.
