Gentlemen: I have been reluctant to ask for help which did not relate directly to our reflector. But today I got up my courage, so here goes. I have been invited to lead a group of amateurs to help
Congratulations on your adventure. In the past, I have seen some of these AM tower efforts ruined by lousy receive conditions. I suggest you get an advance team out to the site to check out the noise
No, I don't believe 240' is too high - especially if the tower has a base insulator! It would be so close to 1/2 wave on 160, that it could be fed very well as a 1/2 wave radiator on 160, either via
I would be especially mindful of corrosion issues in tower planning in the Caribbean. There was a recent article in the Contest Journal on the ever difficult tower corrosion experienced at PJ2T. ____

I recently did almost this same project in Tortola, BVI (VP2V) 4 weeks ago. I have been helping as a consultant to ZBVI for the past 20 years. I was part of the team that installed a new 300 ft tower

Well, he's talking about going in November - maybe in time for CQWW CW -but probably not. 73, ... Joe, W4TV _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________
YES! I had exactly that experience nearly 30 years ago loading a quarter wave tower near Chicago for 860 kHz. Couldn't hear a thing. 73, Jim K9YC _________________ Topband Reflector Archives - http:/
2. In December of this year, I am organizing a small group to go to Haiti and participate in the 160m contest. (this of course is dependent on the tower being built.) December and 160 meter contest
My Inv-L is on a salt marsh on Long Island Sound in Connecticut & I ran two bidirectional 860' beverages over the salt marsh. I had terrible results with the beverages, very noisy and hardly any impr
Half wave verticals have been very disappointing to me over the years when I had the tall BC towers in my backyard to play with after midnight on 160. I have had much better result in hanging 1/2 wav
That's not so surprising Gary !! te Way the Beverages and similar slow-wave antennas work is that they depend on the lossy GND underneath for their operation, so a salt marsh would not be a very bene

Make them shorter and they will often do well over tidal marshes but not over open water. For a 240' tower Id suggest gamma feeding it up at the 1/4 wave point and use 4 elevated radials. It the AM B
I thought a bit more about this while a beachfront/salt marsh location might be ideal for building an international broadcast facility, if you were building a station for domestic Haitian audiences y
Depends on the noise at your location, before I removed the 300 ft towers here I matched one for 160 and ran low power in the Stew Perry a few years ago, ended up number 1 world wide if memory is cor
Of course. I didn't mean to imply otherwise. But in today's world, it is not safe to assume that any given location will be quiet. I've been to mountain tops that were noisy, thanks to lots of noisy

Congrats indeed!! Seconding Rick's comment below -- AM towers make REAL lousy RX antennas. They catch ALL* the front-end-pulverizing noise on 160/80. "Been there, done that..." well, OK, not the dxpe
