This sounds like connecting an antenna to an antenna and I have to assume the SWR match would be badly impacted on both bands. Probably not the way to go. Two other options to consider: 1. No one has

The antenna is a small triangular patch of PCB copper half way along the side of the PCB. Drip a couple inches of insulated wire out of the crack between the side and bottom of the case. Nigel A. Gunn

This thread is about getting wifi connected to a shielded pi (and the mechanical skills required for some solutions.) The video you placed here seems more generic. But I only watched the first 5 secon

sure an external wifi dongle is another option :-) why solder to pi? cause modding is fun (if you are skilled and not fear of modding things) of course ... modding an external wifi dongle (one without

My mail client has been buggy. Determine the chipset name, then search for the Linux driver instructions. 9 out of 10 times it will plug and play. 73 https://duckduckgo.com/?q=rtl+8821+linux&page=1&se

I just grabbed that as a link to show an external USB dongle with an antenna connection. I didn't look further into it. I have tried a few of various makes and they all worked. Other than that, I can'

The adapter's description specifically says will not work with Linux. Have you other experience that it will? Doug KD5OUG

I think I have a couple years on you. I could do it, after practicing on a junk pcb. Would have to use my Mag Eyes and my trusty Hakko iron. That being said, a cheap USB dongle (on a USB extender cabl

I have 60 years experience with soldering, and I would be hesitant to solder anything to a Pi board. But, you can take risks if you like. A simple plug in USB WiFi adapter with an external antenna con

i would use a pigtail and external antenna ... you even could locate the antenna then a bit away from the pi and if needed use a directional antenna pointing to your router (just in case you have the

After a little digging I have found the antenna. Now the question is do I try a pigtail or cut a slit in the case at the antenna location? (Henry Post, please don't bother commenting as you know not o

Normally you can find the wifiantenna at the board edge... On ALL wifi things i have seen..be it a router or a wifidongle.. the antenna was on the pcb edge or corner... Should be easy to find I have a

It's a linear regulator... that's what they do, turn excess energy into heat. If it drops 7V at 1A you're burning 7W. Not sure where you get the 2W number from? 73 de heinz, VK2STM

OK, that''s good to know that you're fully aware of the science. Could have fooled me with a question like: "Reccomendations for metal cases that do not impare wifi?" As mentioned by others, the pi wa

The modern replacement is... A buck converter! Here is the issue - in a linear, you have no choice but to drop the 7 volts as heat, just like the LM7805. The modern way is, gasp, a switcher, aka a buc

There is a "modern" replacement, but would you rather have a little extra heat or more RFI (with generous harmonics)? 73 https://hackaday.com/2015/05/13/hackaday-prize-entry-a-7805-replacement/

Untitled Document The 7805 is not really a wonderful device. Its cheap but its drop voltage seems high to me (7v is needed) and so at 1 amp that’s 2 watts of power and so they run hot. I wonder what a
