Help choosing modern replacement for Hitachi 1SS86 Schottky diode
Visit the site:

They found the following solution:
&quot;NTE112 Schottky diode* (preferred) or 1N5711 Schottky Diode (NOTE: Chanzon 1N5711 diodes do not appear to behave the same as the ST Microelectronics 1N5711 and won’t work. Other good alternatives are the Hitachi 1SS106 and NTE583.)&quot;
I tested other Schottky diodes from Chanzon like the 1N6263, and it was painful to get a very dim light on red low-current LED in a dark environment while uploading massive data from my cell phone to my computer.
I think for uploading, I used: https://play.google.com/store/apps/details?id=com.smarterdroid.wififiletransfer
And for getting more strong Wi-Fi pulse, I used: https://github.com/neilsorkin19/wifiswitcher
(I think due to the Android update police regarding controlling WiFi, this APK will crash on newer devices? I am not sure about that!)
Anyway, I am working on this topic for months. And I took another approach. Because I couldn't find a diode better than the 1SS86, I hope to code an app for iOS and Android. I will publish links to the App at:
lectenna.app
The video that shows that may the 1SS86 is even better than 1SS106, I recommend to you to watch:

It clarifies that with the classical design, you will need to have different antenna lengths on the LEctennas for 2.4 GHz and 5 GHz.
My final tip is testing a LEctenna with a smartphone to use 2.4 GHz because it is more robust and get as far away as you still can upload enough data.

Cross-copy is a useful website for doing tests on the LEctenna as I did:

Just set a password and send the following string from your mobile or tablet to the internet.
&quot;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~&quot;
This string produces quite a lot of data or better-said signals for your LEctenna.
I hope that it helps you a bit. Feel free to contact me.
