Before you buy, site unseen, depending on the brand and condition of the rotor and the Starduster, $150 is way too much for 30 foot of tower and I’m assuming the tower is in good shape for immediate installation, is nothing special, like self-supporting, tilt, or crank up. If it is just some old tower, don’t buy unless you consider the following.
The SD’r could also be worthless and very likely the rotor could be too. This stuff may be very old, the rotor could be Radio Shack type and since you don’t need a rotor, then don’t buy it. You could be paying $50 per section of some homemade tower that might not be worth $50 in total. The SD’r antenna does not require a rotor and I have no idea why the seller is selling it with the SD’r. It all sounds like a gi-me (means screw me) deal. A clue to this seller might be in the reference he uses to describe the other tower, calling it an amateur tower. It may have an amateur antenna on it, but it is just BS Puffing calling it an amateur tower.
Ask how long has this stuff been out of operations and what is the condition of the SD’r antenna, rotor, and tower, by email so you can have a claim in writing if you make a deal. If this is on Ebay, you could have a claim if the stuff is not as claimed and for sure if there is an email claim.
Make sure the tower has very little or no rust and for sure make sure the tower is not bent up or has been lying on the ground. Ask for some pictures or check out the pictures shown really close. Make sure the rotor works or ask the seller for his guarantee that it to work as intended on arrival. If the tower has been stored outside in the weather and the rotor is attached to the tower, then run away don’t walk.
These guys tend to tell you they have no way to check anything and if so, then just walk away. Make sure you get all that goes with the rotor as well, including the wire and controller box if you make a deal.
What brand and model is the rotor?
Again, guys will tell you anything when selling some old radio gear and especially when they say it is an estate sale. Such statements are often used in order to claim later that they had no idea the stuff was worthless, because they were just selling if for someone else and most often that someone that had past and was no longer able to give you answers.
ALWAYS be very cautious in what you buy in old radio gear and for sure if you are new at this. If a little time and maybe 10 gals of gas were not worth the $150, then I would not buy it. Call or email the guy with plenty of questions and see if he will set up a visit without you talking about money. If you get to the location and everything looks good as noted above including the guarantee mentioned, then be prepared to offer the seller $100, telling him you don’t want or need the rotor, and don’t offer him a dime more. If he doesn’t take the offer for $100 dollar bill, then just leave and don’t look back. There will be other stuff to buy when the deal is right. Always tune in for the buzz words being used to sell anything.
