GMRS Antenna question.

[WRVD377]

Since I have little to no knowledge of what is best for a repeater. I initially used what I could find that was "gmrs tuned". Optek UH-2401.

Now after many forums search's I find that maybe a Dipole might be better.

If a person tried to look for the best universal direction output, best gain, and working on antenna altitude, but may not be able to fix that much.

Are my assumptions from my reading even close to reasonable?

If I had the money,

ASP705K might be the best answer.

DB420-B May be next best.

DB408-B Then this.

DB404-B Then this.

Compared to the radiated energy of a Optek UH-2401 like antennas.

Am I missing ground plane / grounding complications?  Other things I am too stupid to know?  Keep in mind altitude is not an option more that 20'9" change to 33'2" mast. Hills North and South.

My assumption is DB404-B in elliptical layout should be better than Optek UH-2401 like antennas.  Is this reasonable  understanding?

Thank you,

Royce

I am going to place a repeater on the top of a 12 story building.

The service area is within the building and less than a mile out in any direction.

Any suggestions on an antenna that could meet these requirements?

I suggest creating a new post/topic so as to not confuse/dilute/drive this entirely different question off topic.

There is a good chance that it won't work within the building.  If the structure is the common corrugated metal with concrete, it will be blocked.  A repeater to work within a building with that structure ... would be adjacent to the building rather than in it or on top.
