Hi Bob I remember reading a story a few years ago where a guy put in a short tower. Every day, he went out and watered it. One day his neighbour came over to ask what he was doing. The guy explained

I recall seeing a picture of an OH station running a pair of stacked two element 80's. Pictures on the net - will see if I can find it again. Something not for the faint of heart! Tom - VE3CX _______

I would be VERY VERY careful about recommending anyone hand dig such a hole. If the walls of the hole cave in, you will literally be digging your own grave. There was a bit on the local news last yea

Hi Jeff I shunt fed my 64' on 80, and found the signal levels from it were well below my half-sloper on another tower. I spent quite a bit of time trying to get it to work on 160, and in the end, I g

Hi Doug In doing some research on various antennas, the half-sloper was described in various texts as a "bastard antenna". As you indicated, works well for some, not well for others. One person spent

Hi Bill Hi Bill I understand the difference between aTH6 and a TH7 - the later has an extra driven element so you can get a flatter SWR across the band. IMHO, it seems like a waste of money. I picked

Hi Jorge There are two ways to tackle this problem. The first is to add a second Sixpak - this will give you eleven ports total. The other is to add a remote coax switch, and install it on the ports

Hi Dick I have a shorty fourty at 80 feet. The biggest thing I find with it is that it does not cover the whole band, and performance is so-so. I set up a single vertical, and like you, found it work

One thing that is interesting is the height of the antenna - moving the shorty 40 higher seems to play an important role in how well it performs. Will have to see if I can get mine a bit higher this

Sounds like you had a larger antenna than this rotor was designed to handle. Take a look at a larger used rotor - say a Ham IV or Tailtwister. They are quite reasonable on the used market. Tom - VE3C

Here is something to try. Lets assume you want a 66 foot radial. Cut off a 66 foot piece. Attach one end to a fixed object - say a tower. Stretch it out, and put the other end into a variable speed d
