Feeding a HDMI cable through brick walls? Drill big holes or chop/solder?

Replacing an old RF Coax cable that goes through a wall to the outside of the house for a TV in the kitchen.

HDMI has a slim but wider block and was thinking either chopping the cable a metre from the end and solder it up or drill a bigger hole and use filler?

Anybody know an easier method?

Use a cable with mini hdmi on one end and then a female adaptor on the other side of the wall?

Run the HDMI over the existing coax?

Hmm, might be an option with reverse terminals so no drilling as it will fit standard holes.

Thanks.

Forgot to mention I have got flood of a standard 20m hdmi cable and an old hdmi splitter for my Virgin box.

Put a HDMI socket on the wall?

Ok I’ve checked the current hole; it fits 2 RF cables that with a bit more drilling might be able to expand it a few mm to allow the cable through.

If I was going to start from scratch and didn’t already have the hdmi cable (and to help others):

I’d use a hdmi splitter, HDMI to Ethernet box and cat 6 cables that are quite slim.

Didn’t want to pay £££ for AV sender when my wifi is 5ghz and the neighbourhoods 2.4ghz interference.

surely the cheapest is a mini hdmi to hdmi cable + mini female to hdmi something, either just a converter back to standard hdmi, or another cable. they are tiny, defo will fit. Should be do-able under £10.

How long is the run to the Kitchen?

20 metres externally.

I’ve tested the cable and signal is great on my 25m cable using a powdered HDMI splitter.

You’re right Doc, it’s the cheapest but might try with I have first.

Just an update:

Took a gamble and chopped the wire 1 metre from the cable box so I didn’t have to drill.

Spent 20 mins trimming the little wires and soldering.

Works fine even without a signal booster and just a simple splitter.

You can buy block connectors to save your eyes from strain when soldering.
