While pondering the design of a broadband antenna that would cover
from 50 to 450 Mhz I considered a log periodic array. This would serve
my purpose but the size would be inconvienent. Then I had a thought,
Could I remove the elements that are not required for amateur band
coverage? In my case I am only interested in 50, 144,and 432 MHz
bands, Would this allow me to shorten the boom by an amout equal to
the space occupied by the removed elements and have a gain of 7Dbd.
Could I cover all 3 bands with just the elements for 6 and 2m?
Any thoughts on this would be greatly appreciaated.

No, you need some coverage to provide the gain. Think of a standard
yagi, without the reflector and director it's just a dipole. Personally
I built one almost exactly like you are talking about (25 years ago),
the performance stunk and I scraped it
