    My QTH is out in the country on a hill. I'm within the top 10% elevation for my county at 800 feet above sea level. My neighbors are at least 200 yards away. There are no antenna restrictions where I live. Right now, I'm only using a 20M center-fed dipole and doing fairly well. My rig is an Icom IC-7300 and an Acom 1010 amplifier rated at 700 watts PEP, but easily peaking 800 watts with a 50-watt input. I have an uninstalled 50-foot tower -- one of those galvanized tri-leg TV towers you used to see everywhere. I can add a 10-foot mast to the top if needed.

    I definitely want 20M and 10M (for when it opens up great.) 40M is desirable, but I'm not sure I can work a bunch of different bands into this antenna. A directional yagi-type antenna would be a huge plus! My budget is $2500. What would you buy?

    What other bands are you curious about?

    Tower tribander yagi wire fan dipole for 40 and 17. Probably find a used tower cheap. You could go the hexbeam route but I question the long term durability.

    Is that for the entire project including a tower foundation, cabling, rotor, lightning protection, etc; or is that just for the antenna ?

    I've only used 20M so far, and really like it, but I always hear talk about 10M being great at the peak of the cycle. 40M is probably a given. Being a new ham, I know nothing about things like 12M, 15M, 17M, etc.

    Not really. I didn't add concrete into this budget, and I already have 150' of LMR-400. I can always scrape up funds for a rotor outside of this budget as well. So, let's say $2500 for antenna at this time, with less not hurting a darn thing. LOL!

    17m has been the new 10m for the past several years. My favorites are 40m and 17m. I'd opt for a horizontal wire as high as possible for 40m, and a light weight beam on your tower for 20/17m...

    I would do the tower with a tri-bander such as the Mosely TA33 at the top and an inverted vee cut for 3.5 Mhz fed with 450 ohm window line to just outside the shack with a 4:1 current Balun and the rest of the way with low loss 50 ohm coax . That should be good for several bands .

    You have to be careful with a "TV antenna tower" and an HF beam.

    Depends on the exact tower design, but many of the old "TV antenna towers" I've seen are too skinny to even mount a rotator inside them, so a rotator would have to go "on top," above the tower. Some are also too small to withstand much in the way of a rotating load that tries to twist the tower into a pretzel. Some are too small to be guyed and were really intended to be bracketed to a house.

    But designs varied all over the place.

    Do you know the model number of the tower? Or can you post some good, clear pictures of it, along with a measurement of leg-to-leg spacing (center to center of the upright tubing) across one face of the tower?

    I'm at work, so the only photos I have are what is on my phone. I think the leg-to-leg measurement was around 11-12". I *don't* have to use this tower, but it should would save me money over a Rohn.
