    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

After alot of hard work and alot of fun my tower is up. In the following pics you will find a 50 foot total height Rohn 25G tower. The tower contains a AS-1405 225-400Mhz log periodic that has been tweaked to be mounted tower top. Below that antenna is a 900Mhz yagi for undisclosed purposes:). Down the tower is a scantenna that will soon be taken taken down. (I hate scantennas). And futher down the tower there is a PAR SWL HF longwire. And soon to be mounted at the top of the tower will be my newest antenna that is being built by the guys at KMA antenna as we speak. It is a 12 foot boom 225-400Mhz log periodic antenna that was originally designed for Northop. All of the directional antennas are turned by a CDE Ham III rotor. The tower is set in a 4 foot square hole that contains a bit more than a yard of concrete and heavy rebar cage. The ground system that is not yet complete is a series of 4 10 foot ground rods all bonded to the service ground point of the home. A proper ground is very important. So far performance has increased. With better height and being able to turn the antennas I can see a good increase in range. And special thanks to Brent or on Radioreference you know him as "123". We worked till after dark tonight hanging antennas.

Here are a few pics here and follow the link for all the pics...

I would get more than just one ground rod for that. You might try getting some bare #2 awg copper wire and use an edger at an angle and a broom handle to push the wire into the ground, then tamp it down. Should have several pieces, otherwise, a good job. You need more antennas up there.

Zguy,
Great job on the tower and is done perfectly. Nice and clean. One question, what is the PVC pipe beside the tower leg with the little rain hood, for cables?
Again awesome job, wish I was there to help you guys but looks like you and 123 did not need any. By the way, great pics 123.
Take care
Ron

No guy cables?

I don't see any...
You are braver than I..
There is NO WAY, I would climb a 50 foot G-25 without guy cables.:eek:
None, zip, zero, nada.
Remember me in your will.:p

DANGER
No Tower is self supporting during construction! Always use temporary guys on the top most section,
and install permanent guy wires as soon as a guy point height is reached.

Its not a 50 foot tower. There is only 36 feet of actual tower above the pad. The mast did account for the rest before it was cut shorter.. No worries here. I am within Rohn specs.

Thanks for the advice though.
