Question NAV antenna for SL-30

Hello,

I have to order soon the COM and NAV antena for the SL-30. As the SL-30 have VOR but also glideslope and ILS features, which antena will be the best choice?? a common VOR antena is enough ??

Any suggestion will be welcome, thanks

"Best" is subjective, but the wingtip Bob Archer VOR antenna works great for me in my RV-7 with the SL30. As you probably know, the SL30 has an internal diplexer, and all you gotta do is run one coax wire from one antenna to the radio, done deal.

Thanks Dan,

But I'm thinking using an external antenna for the VOR / GS / LOC
like: the Comant CI-157P or the AV-12L from RA Miller,

then the CI-291 or AVT 10 (from R.A. Miller) for the VHF com.
and the COMANT CI-101 or CI-105 for the transponder

What do you thing about that?

Well, you asked what I think, so here goes... I think it's silly to put an antenna on the outside of a plane when it can be inside a wing tip and function as well. The whiskers are just an eye poker in my opinion.

If your gonna go external, go with the expensive flat blade type, they look the best.

Default Make them yourself

An extra advantage of this antennae is that you can make them yourself. They work very well and you don't have more stuff hanging into the breeze. If you can build a plane, the antennae are simple.
