Specific information is available on line.  Here's the text.

US7 In the band 420–450 MHz and within the following areas, the peak  
envelope power output of a transmitter employed in the amateur service  
shall not exceed 50 watts, unless expressly authorized by the FCC  
after mutual agreement, on a case-by-case basis, between the District  
Director of the applicable field office and the military area  
frequency coordinator at the applicable military base. For areas (e)  
through (g), the appropriate military coordinator is located at  
Peterson AFB, CO.

(a) Arizona, Florida, and New Mexico.

(b) Those portions of California and Nevada that are south of latitude  
37°10′ N.

(c) That portion of Texas that is west of longitude 104° W.

(d) Within 322 km (200 miles) of Eglin AFB, FL (30°30′ N, 86°30′  
W); Patrick AFB, FL (28°21′ N, 80°43′ W); and the Pacific Missile  
Test Center, Point Mugu, CA (34°09′ N, 119°11′ W).

(e) Within 240 km (150 miles) of Beale AFB, CA (39°08′ N, 121°26′  

(f) Within 200 km (124 miles) of Goodfellow AFB, TX (31°25′ N,  
100°24′ W) and Robins AFB, GA (32°38′ N, 83°35′ W).

(g) Within 160 km (100 miles) of Clear, AK (64°17′ N, 149°10′ W);  
Concrete, ND (48°43′ N, 97°54′ W); and Otis AFB, MA (41°45′ N,  
70°32′ W).

So, 435-438 MHz is available with limited output power.  No limit on  
antenna again, that I see.

I hope this helps.

What we can do is to live out our lives as best we can with purpose,  
and with love, and with joy.  We can use each day to show those who  
are closest to us how much we care about them, and treat others with  
the kindness and respect that we wish for ourselves.  We can learn  
from our mistakes and grow from our failures.  And we can strive at  
all costs to make a better world, so that someday, if we are blessed  
with the chance to look back on our time here, we know that we spent  
it well; that we made a difference; that our fleeting presence had a  
lasting impact on the lives of others.
