Is a longer antenna always better? Would extending this beyond 25cm improve the signal reception for this car? (Operating frequency is 40MHz)

This is a shorting bar that grounds utility 240VAC aerial cables to the ground. Spare operator required per use.
It also acts as an adjustable, rotary V dipole, based on two alix telescopic verticals.
It should be extensible, but we never used it beyond 10m so far. Based on an idea by @yo9lig
As planned, I spent part of my day today home brewing a new VHF/UHF base station antenna. It was an easy project, and initial testing suggests it works great.
I wrote-up a complete description of the project, along with several photos. Take a peek here: https://querybang.com/2025/03/a-home-brew-vhf-uhf-2m-70cm-base-station-ham-radio-antenna/
Now, time to get to building my new DX Commander R-r-r-r-r-r-r-rapidé to go with it! 
... itz called minimalism y'all ... don't knock it .. it affects the downloads ..

Looking forward to turning this pile of hardware into a new VHF/UHF base station antenna tomorrow. Something to do while I wait for UPS to deliver my new DX Commander Rapide for HF.

Anyone know offhand, if an FM radio station is broadcasting from a hilltop to the northeast, how should I orient a standard cheap floppy wire dipole for best reception?
Assuming the antenna long axis is vertical, should the arms of the “T" be perpendicular to northeast?
Also, how could I couple a dipole to a clock radio with a short single wire antenna and no antenna terminals?
I personally watched someone use an air cannon at field day to put an antenna wire over a tree. So yes, this video is made as a toy but they can be useful.
I've seen slingshots used as well and dog toys. I watched someone use a long plastic pipe extension gizmo. I guess pick your tool. ;)

#hamchallenge week 12 will be an easy one, after a few more difficult challenges in the past weeks: Make a #hamradio contact (QSO) with an "unusual" #antenna. Load up your bed springs, a light bulb, your house's gutters... there are no limits to your creativity in this challenge. Looking forward to hear what everyone did. Good luck! https://hamchallenge.org/2025/12
I'll keep an eye on it in the next days.

Still no box, that will come when I stop experimenting...
Let's see it if made any difference (just hope I didn't make it worse...)
I scraped the #wifi #antenna contacts and cut the trace going to the rest of the internal antenna. Then soldered the cable with the #sma connector savaged from the #fonera . The shielding of the cable goes to GND (used the multimeter to find which one is GND) and the inner to the other antenna contact.
I imagine -92dBm is not a really good figure
The electric box is at the end of a far corridor, in a part of the house where noone hangs around, so I'd prefer not to place a #WIFI repeater there.
Tonight I'll try to solder an external #antenna to the #esp32 like explained in the #homeassistant forum: https://community.home-assistant.io/t/how-to-add-an-external-antenna-to-an-esp-board/131601
I'll use the #fontenna (it's the #fon #fonera external antenna I savaged when I... ehm nuked the fonera flashing a firmware in the wrong partition
). Will see if it improves the situation...
