Just as September was ending, I spent quite some time on small HAM projects.
1. I received the connectors and cables I ordered, so I sat down making cables for each DIY antenna I have.
2. I used some leftover PVC pipe to add 2 more sections in my collapsible antenna pole. Each section is 130cm (about 1.5 yards long), the wider my car trunk will allow. That makes for about 7 yards total height, just short of what one would need to make a sloping longwire antenna.

This is just a undocumented idea.
Assuming that a dipole has an impedance of 75ohm, which turns to 50 when it is made into an inverted V, why shouldn’t one make an inverted-V VHF antenna and then turn it 90 degrees for vertical polarization?

This is just a quick project. The past week I made me two DIY wore dipole antennas for the VHF.
The lower one is of solid core wire and a Banana-to-BNC adapter. After “tuning” it with my SWR meter it will be disassembled and stored.

Here are photos of my latest build.
