Antenna Info for those who care

[Korey Curtis]

Hello fellow ASW15 flyers and Kamakinzi (AKA "Dust Boy"),

I wanted to share my findings and research pertaining mounted antennas within the vertical stabilizer...

I recently bought a new radio for my ASW15B. My glider came with a antenna with coax routed up to the front. During installation, I ohmed out the coax and found a direct DC short. I then asked Dust Boy to ohm his ASW15A gliders coax and antenna to see if it had a DC continuity short... it didnt.

After researching, which i should have recalled from my EM (Electromagnetics) class, I relized that 1/4 wave mono-pole antennas DONT have DC continuity while 1/2 wave dipoles do have DC continuity. I wont get into the gory details but just keep in mind that just because you get a DC continuity reading when 'ringing' out your antenna, dont mean its bad. RF continuity is not the same as DC continuity. Just wanted to share that with anyone that really cares.

The GOOD NEWS is that my glider did have a dipole and my new radio connected up to my stock coax/antenna works like a charm!!  :laugh:

Sounds great....
I was picking up Hill Feild and listen nightly to approach while i load test my battery. Got about 4 hours now on the battery and still holding up okay. Its a 7AHr battery but was used so wanted to make sure it works.

Dropped off my O2 this morning up by your house. Praxair isnt the best service ive ever had. Want to buy a large tank thats filled so we can leave it at the airport... would you be interested in chipping in on this? I figure if we get 4 or 5 of use to go in on it, it shouldnt cost much to get a large tank... thoughts?

Sounds like the wing is getting there... very excited to get going this season.
