My husband built a homemade antenna for his ham radios.
Keep in mind, I am not a geek so I'll describe it as best I can with his help.
This is a J-pole which is a half wave/quarter wave antenna, which is one of several types.
You have to calculate all sorts of math stuff in order to come up with the best antenna to resonate at the frequency that you are trying to work. Again, I'm not geeky so I hope you're following.
This will allow him to broadcast much farther than he was able to with the smaller antenna.
He started with 10 ft of half-inch copper pipe, 1/2 inch copper Tee, a 1/2 copper 90 and three 1/2 copper caps. There are some copper clamps and pvc pipe plus 50 ohm coax cable. The pvc pipe is a 10 ft piece he had laying around the house. He soldered everything together. He had to do all sorts of adjustments to make sure he would not damage the radio with the the power he was using. It's sort of like getting a clogged pipe that can leak back into your house and destroy it. The same for the radio and electricity.
Then he and drove a t-post (fencing) into the ground and slipped the pvc pipe over it.
He drilled a hole through the foundation and connected to the radio.
In between all these steps are again lots of geeky stuff that had to be checked and adjusted.
All in all, he's been able to transmit 30-40 miles whereas his smaller antennas might get that distance but not in the same direction (toward the city) due to whatever interference would block the signals.
If he decided to put the antenna on the (very tall) roof someday, he'll be able to reach even further, especially since we're on the ridge top.
This is the new radio shack in the man cave (basement). The table is made from an old door that was being thrown out on the job site. It fits perfectly in the alcove created beneath the first floor fireplace. He will add shelves for additional storage.
The antenna comes through the basement wall (follow the cord above the radio)
Just a few of the books he has.
There are many, many more.
And, with one simple turn of the chair, there is a pool table, and the stereo and a fridge with beer.
What a coincidence!
