J pole antenna to boost smart meter signal ?

[Kaney]

HI, I am in the UK, in a long range radio deadspot so my smart meter will not communicate with the DCC. I should receive 423MHz from the Bilsdale transmitter in North Yorkshire but, as my meter is inside the house housed in a cupboard, nothings getting in or out. I know nothing about long wave radio, antennae etc. but hope someone can tell me if I do this - credit to Jeroen Steeman - put an extended version of the J-Pole antenna, using the same matching stub principle with the length of the antenna being three quarter wavelength - attach it to 75 ohm coax as he advises, run it to the smartmeter and duplicate the aerial connection at the other end, will it help increase the signal strength to the meter. We are not allowed to connect to the meters comms hub and it has a tamper device fitted, so the antennae will just sit near to the comms hub. So, I guess in some way, it just 'transfers' the signal from the roof down to the meter cupboard - is this how it works ? Just one other thing, does the ariel Jeron suggests need to be aligned in a particular way - horizontal v vertically, at right angle to the direction of the transmitter or parallel with it? Any help gratefully received..Thanks

Several internet photographs of the J-antenna show it oriented vertically.
Implying it's omnidirectional.

Sounds like you need gain as primary concern, then Yagi or Log Periodic
will get you a lot more G and noise reduction via beam width over a
J pole.

A very helpful reference :

These antennas would be pointed in the direction of target. More finer points
you can look into propagation regarding azimuth considerations.

Something like this for outside on the chimney https://www.antennaexperts.co/product/CY-450-Datasheet.pdf
Then a folded dipole or half-wave loop near the meter should work.
If you have 75-ohm satellite cable use that.

Thank you all for taking the time to reply - I think I'll try to source a Yagi for the roof and try to make a j-pole for the cupboard and connect them via 75 ohm cable. I'll let you know on this thread how it goes once the meter installation team attempt the connection again. Best regards.../Pete

Use low loss coax, like RG11, LMR400....no point in throwing away hard
to win antenna G in cable loss.
