Today, I put together a new portable repeater antenna setup together. I do a lot of work with Amateur Radio Emergency Service. Often, we need a repeater setup so our people can run around with HT's and still be able to communicate direct with everyone.
The antenna is setup for 2m, 70cm and GMRS. In all services, the SWR is 1.2:1 or better. It's sitting on top of a fiberglass mast.
The total height is 47 feet from the ground to the top of the antenna. The bottom of the antenna is 40' from the ground. My son Nick is next to it to use as a reference.
I tested it out on 2m. Full quiet to another station 40 miles away, with only 5 watts. I'm pretty happy with that. On 70cm and GMRS, I was full quiet to a repeater 22 miles away with just 2 watts.
I am pretty happy with this setup. I am going to be doing a training drill on March 28. We'll see how it goes.
