As Taxsrv noted, your current antenna "sucks for both VOR and ILS". Let's
explore that before we design you something that will suck for the same
reasons.

Questions for Jim Weir, or other knowledgeable folks:

I've got a couple of questions about an ideal antenna for ILS use.

My Comm/Nav radio uses one antenna for both ILS and VOR. I rarely use
VOR so I'd like to optimize an antenna for ILS use (a side note -- my
current antenna sucks for both VOR and ILS). My plane is fiberglass.
I'm thinking a "V" shape may give me a stronger lobe toward the front
but don't know what the angle should be.

So, my questions

Is a "V" array a good idea for directional gain? What angle?

Should the top of the "V" be oriented forward to maximize reception
from that direction?

How long should the elements be for optimum reception of a 109MHz
signal?

Thanks – Bill Kennedy
