Even when I was a radio ham in the 60s, I hated RF. I couldnt see it, and at 10watts on top band - I couldnt feel it.
I could work out the exact length for an antenna, but then found you have to trim it afterwards ! I much preferred logic circuits, all true false and no maybes.
Some time later I worked on the Boeing 707, which had a horizontal whip that stuck out horizontally from the top of the tail, but was found to emit vertically polarised signals ! I hate RF.
50 odd years later, I am using 433 MHz links in many projects. I came up by accident with a fantastic whip antenna for the remotes, with which I get good range, and they cost the price of a BNC plug, plus 160mm of curtain expander wire, with a rubber bit on the end to save peoples eyes .. It looks cool and can't be easily damaged.
At the receive end, I usually just have a 160mm or whatever length of wire behind a plastic LED display.
Now I have made some units that have the transmitter in a box behind the display, and I am assuming that the front of the display board will be Chromadek ( metal ) so I am fitting the antenna inside the display , and want to run a 1m length of RG174 coax to the transmitter behind.
The shield of the coax will be grounded at the TX end, but for the life of me I can't remember what to do at the antenna end in the display.
I can just let the centre wire stick out for 160mm, or I could ground the shielding on some metal at that end.
Of course I can try it and see, but if there is a preferred method I would appreciate having my memory jogged !
