To be sure, I was fixin' to insert a smaller-diameter pipe into the top 10 feet, to give it more beef. What do you think of that?

Yes.... it's actually the 1.9 inch stuff. And the top of the mast will be about 9-feet above the highest wall-bracket, with the A99 antenna attached to that.

So, do you think I'm OK with the Schedule 40 stuff? Attached is a picture of my plan.

It is said that Aluminum Pipe even at Schedule 80 would be much lighter.

I just got some Schedule 40 pipe from the local plumbing company. It's very heavy, but I'm concerned: Holding the 21' foot pipe, I can make it wobble when I shake it. Hmmm...

Where do you get such stuff? Any stores online?

Do you reckon Schedule 40 water galvanized water pipe will be sufficient? What do you think about this: Using Schedule 40 pipe the whole way up. But for the 10' portion that extends beyond the roof, insert a another Schedule 40 pipe INSIDE the main one. Plug-weld or bolt it in place. Do you...

Do you reckon Schedule 40 water galvanized water pipe will be sufficient?

I will soon install my A99 with Ground Plane Kit. I need a mast pipe that will be 36-feet tall. It will be cemented into the ground, bracketed to side of house, and appropriately grounded. About 10 feet of the pipe will extend beyond the roof line, with the A99 antenna on top of that. I'm not...

Thanks. The base of the antenna will be about 31 feet above the ground.

What kind of pole did you use? How thick was the wall? What was the diameter of the pole?

I'm fixin' to install my new A99 with the Ground Plane Kit. It will be attached to a steel pole that is 31-feet tall. Will have in-line polyphaser. Pole will be cemented into aground and bracketed to side of house. Should I isolate the antenna from the mast pole? Is there a benefit? Is there...

Can you explain, "easier to work with," and "use friendliness"?

What do y'all think of the coax made by DXEngineering? For example, their 400MAX, which they say is the equivalent of LMR400.

What is the absolute best coax for my base station running on 4 watts to A99 with Ground Plane Kit. I want the absolute best! I'm only running about 27 feet from radio to antenna, with an inline Polyphaser. I want the absolute least amount of loss. So, what's the best coax and where should I...

Thanks, Marconi. I need a bit of help in understanding your pictures. With the GPK.. it looks like the radiation pattern is extended more than w/o the GPK... but I'm not sure if my interpretation is correct. I"m also a bit confused by "isolated from the earth." I always thought that it was a...

How does common mode currents effect performance of the antenna? What do you mean by "stabilizing effect on the antenna above them"? And what other benefits does the GPK give the A99?

I'm almost ready to install my new A99. Even thought the A99 is not the best performer, I like it because of its proven physical durability. I've had one on the house for 25 years with no issues from hurricanes and winters. I now also have a new GPK with my A99. The new A99 will be attached...
