So, after putting my cell phone in to use and running RTL-SDR radio listening apps, it was time to make 2 antennas for the dongle, the original one being Poor.
So I got me a coffee, nerves of steel, and started soldering on two MCX window Connectors for RG-174 cables.
The wire was sourced from a surveillance camera installation cable. It has 3 single conductors and a coax wire that seems to be RG-59 75ohm one.

I will guess that more than half the people that tried to program one of the Baofeng failed victim to the fake programming cable chip plague.
It happened to me also, and the process of finding a working driver, to no avail, killed my will to move further.
Enter the Baofeng T-1 mini radio and its programming cable that really worked!
Since it terminates to a mini-USB connector I quickly formulated the plan to hacking it for my UV-5R and UV-3R radios.

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.
