Helo! Is everything okay with you?
Please are you able to develop an antenna or array of antennas for the 920 to 930mhz range with an excellent gain using Flexible Polyamide or Semi-Flexible FR4?
See the antenna concept drawing and the location where this antenna will be placed. Is attached.
The place is a product of my client, entirely in steel. I already did a test with an array of spiral antennas improvised with coxial cable and got 4km of range.
My challenge is to get 8km of communication.
Can you help me? What would your price be?
