Both are good antennas. The AP being 5/8's wavelength has more gain than the Starduster. The AP would be easier to assemble and put up on a pole. But either would do a wonderful job. Right now, knowing what I know, I'd choose neither one but go with the Imax 2000.

Between these two... It depend on mounting height and how much wind you get.

Lots of wind or low to ground, the Top One. High up and not much wind- Skylab.

How well does the Top One perform at a height of 51 feet at the feed point?
I know that the old astro plane done real good at height about 30 feet but I dont know about any higher

I have an original astro-plane up about 50' at the feed point and it does real well. I live in the bottom of a valley and talk to lots of folks on the CEF net every weekend with good reports. I also had the astro-plane when I lived in Oklahoma on a hill and it did a very good job there too. Great antenna, if you ask me. My dad bought it back in 1973 brand new for $17. It's been through many thunder storms and lots of high winds and I only had to fix it once when the flattened end of the hoop broke off ( after 22 years of service).

Great antenna in my opinion.

I have the copy (but it looks just like the original after i beefed it up) adn i have mine with the bottom hoop at ONLY 2' off the ground and have talked to a few locALS 12 TO 15 mile away and give them an s 5 to a 7!!! Great antenna IMHO..

Copper sells some kind of switch box that lets you use two radios on the same antenna system. This might keep you from having to install another antenna.

My pdl-2 boom at 40 feet,I guess that would put it at a height of 47'.Quary:I live in a valley 457' above sea level,what would be the best possible omni antenna for my area,no obstructions above 12',and moist sandy loam soil year round,high iron content even when it's 30 below out the ground never freezes below 1 or 2 inches.Bigbob

The reason I asked the question is I have enough extra mast to get one up to a height of 51 feet at the feed point at the feed point. And Im kinda fond of aluminum antennas they seem to have better receive in my book. And of course using a very good RG/8 type of coax. And where I live we have some very high winds in the spring time its right in tornado alley.

over the years i have tried them all. each antenna has there pluses and minuses.but when it comes to fiberglass antennas 16 foot shakespeare,pogostick,three section bigstick,archer crossbow,[blue] none of them lived up to expentations. always ended putting the aluminum 5/8 wave back up,but had to live with swr swings during rain or ice. so i reluctently ordered a i-max 2000 and thought probably another disapointment, WRONG,signal reports were either equal or within 1/2 s-unit, local. and swr stays almost the same no matter what the weather is. the only modifacations i made was i used stainless washers between the sections and wrapped the bottom section in electrical tape and painted the other two sections,to ward off uv damage. hope this helps.

Im seriously thinking about getting another I Maxx 2000 and giving up on my astroplane... I had one once and love it best fiberglass antenna i ever had. I just get sick on my SWRS going nuts on me when it rains or snows..... Ill slap some GR 9913 coax on the bottom, put that I Maxx up about 30' on a pushup mast, guy it, and be happy once again..

Cm3885, that's an issue that comes up over and over again with me and aluminum antennas. The weather just kills them. Rain affected the swr on AP. Good antenna, in fact, I wish I had a spot in the yard just to put it up close to the ground where it works best, but I would go with the Imax in the blink of an eye if I needed to buy another GP.

There's an older man in our community who is about to replace his old A-99. We're trying to talk him into the Imax 2000. He's complaining of having no ear. He's running close to 100' of the small mobile coax. I told him that was probably more of his problem. But I think he's about decided to to get the Imax 2000 and some better coax. Me? I've learn my lesson again this about coax. Whenever I ever buy coax ago it will be the very best. Why lose even a half of a db in your line? Every bit of signal counts.

I'd bet if someone bought an Imax 2000 and treated the fiberglass with that primer mentioned on this forum that the Imax would stay in one piece and work for 30 years.
