Can somebody please identify this antenna

[KeithJoseph]

I just recently got it from a friend and I don't know what it is other than its base station.

Can you let us know how long it is, how long is the aluminum portion?

I'm 6 ft

Any labels on it?
What kind of connector? How many connectors?
It looks almost like a FAA VHF air band sleeve dipole but I think it's too big for that.

It looks like the base portion/matching section of an old Antenna Specialists VHF low band 1/2 wave vertical. If so it would have three threaded holes around the bottom for the ground radials and it had more aluminum tubing sections on top to make it a 1/2 wave between 30 and 50MHz depending on version. It should also have pipe threads on the bottom to mate with a threaded mast.

Ok that sounds right I've got two more metal pole like things that I think go to it but idk how to make it work.

Okay so is this antenna better than the discone that I've already got

I used to have the instruction/tuning sheet for the A/S VHF lo antennas but would have to search for it. You would need the three ground radials and they adjust to about 1/4 wavelength long for your frequency of interest. The vertical section was a little over 1/2 wavelength long including the grey plastic base portion. These came in at least two versions, one for the lower end of the band like 30-40MHz then another for 40-50Mhz I think. I had a high split model that I put on 6m amateur and it worked ok.

It would be much better than a scanner type Discone for one specific VHF low band frequency + or - about 1MHz. That's it and it would be useless for anything else.

I get confused about frequencies and such. But here is some more of it

 

[prcguy]

Looks like you only have one ground radial out of the three and its really long, so you probably have the 30MHz range version. The antenna is an ASP-600 series and it came in three versions to cover 30 to 50Mhz and had an A, B or C suffix. If you have the A version it would only be good for receiving a frequency within the 30MHz range or it might tune down to CB. Measure the skinny ground radial with the threaded end and let us know how long it is.

It's a little bit over 2 yard sticks long

So how much is this thing worth?

 

[prcguy]

Its probably tuned around 36 to 39Mhz. Someone would have to make two more ground radials or probably three so they all match, then you hopefully have enough of the top sections to make it work.

I would say if all the parts were there in really good condition its worth maybe $75. If the parts you have are not damaged or full of water and corrosion, maybe $25 since its a big project. That antenna is also very obscure and it will be hard to find someone that even knows what it is.

I had one up for a few years here then took it down and it laid on my roof sideways for a few more years. The ground radials were so badly corroded they would not unscrew so I broke them off, cut everything up and put it in my recycling trash can.

[KeithJoseph]

Well I've got it for sale. Or I would probably give it away honestly. I have no use for it and it's just in my way.
