I had/have 2 beams pointing at the horizon. Both WERE vertical for repeaters but then I went out and got myself a 9700, it took me back to my roots from the 70's working weak signal stuff on two, AM with 20 elements, that was a long time ago. Recently, I decided to dabble or try to hear the birds on my tri-band vertical. I heard them pretty good. It was then I realized, my now horizontal beams would probably be better for the birds at low orbital altitudes from my QTH. I found that they work fabulously for those low birds and work good even up to direct overhead birds. However, I am not entirely satisfied so I decided to build two eggbeaters for the high birds via a switching arrangement. Coax to both or all is RG-8u, only about 45 feet for the beams and for the eggbeaters (since they can be mounted just about anywhere), about 20 feet.
