So ... the first thing I did was to establish a baseline... this would be the Vee Dipole VOR antenna. With the folded balun. The antenna was tuned for best VSWR in the VOR band... the attached pic sho ...

Just an update... I am currently pursuing a loop antenna made out of Coax which allows me to reduce it's size somewhat. I am looking at placing this antenna inside the fuselage tailcone (all composite ...

So the plan would be to drill 2 tiny holes in the wing skin and feed

The wing is all finished, using premold ...

A technique used by some boat builders to form pillow blocks for prop shafts is to coat the shaft with wax of sufficient thickness to assure clearance between the block and the ...

Thx... I am actually thinking of using the braid only as the antenna material... as part of making a proper balun one would only use the braid to connect to the antenna elements anyway while the cent ...

Ok... got the bandwidth angle... as planned now it would be installed in tension mostly...

my other option is to use part of the coax itself as the legs of the V shaped dipole

If you want I can take some close up pics to further illustrate what I am telling you. Cheers, Larry N852LW

That would be greatly appreciated. Thx

So the inspection plate assemblies came with your Pulsar III kit?... I have a Pulsar XP and was wondering if I can/should do something similar... the questions really is how the wings differ on the tw ...

Larry,

That looks like exquisite workmanship!

Would you mind sharing more details regarding your install?

For example, is it attached before or aft of the main spar? Where did you route the t ...
