A question about VHF/UHF antennas?
I have a dual band yaesu (144,440mhz) with 50 watts output. I was planning on installing a single antenna just for 440mhz operation (2m is going to relatively unused for my purposes) I plan to put a half wave dipole up at about 30 feet for 440mhz. I am using #16 copper antenna wire fed with 50 ohm coax (probably rg-58).....i want to shield the antenna from the elements by encasing it in 1/2 inch pvc pipe (i will feed at the center through a small hole in the pipe and cap both ends)........what i am wondering is will thus hurt my performance at all?......the radiating element will be completely encased in pvc...... i know some pvc manufacturers add metal filings to the plastic to meet strength requirements but i will be sure to get pure plastic....so hoe much would this design hurt my performance?
yea, that will work just fine.
Test the PVC pipe first. Put a piece in the microwave oven for a minute, if it gets HOT, it will nnot be good for antenna work.
Rather than a dipole using #16 wire, I would build a "J-Pole Antenna" using 300 ohm TV twin lead.
I WOULD NOT use RG-58, the attenuation at 30 feet on 440MHz is about 6dB. That means that 50 watts to the antenna, 12 watts gets to the antenna.

You can put the j pole antenna in a piece of PVC.
When I build antennas in PVC, I paint the finished antenna with clear Krylon to help protect the antenna from UV light rays.
