Affect of reception due to weather.
« on: May 18, 2011, 04:58:11 PM »

Meant to post this here!   
   


Hi,
I don't remember seeing comments on this subject. Does the weather have a great affect on reception? I have recently acquired a new DPD antenna and it has increased my range and number of flights in My flight log. We are unfortunately in a weather pattern of 7 days of overcast and daily rainfall of approx .5" of rain a day. If the sun ever comes out again here in central Ma, do you think the range will be extended further?

Thanks
Sherlock Holmes

There is no doubt that rain and snow will attenuate signals at this frequency.

The new antenna will be fantastic when it finally clears. It has increased my range out to about 100 miles from 60. The myflight log has doubled and my msg/second has shot up. Excellent antenna!

Hi airnav1967,
I recently purchased an antenna from DPD Productions:
ADS-B (SBS / RadarBox) Vertical Outdoor Model Antenna  $149.95 U.S.

http://www.dpdproductions.com/page_vhf_air.html

I've only had it for a week now but what a difference it has made.

Hi,
I have read several post over the last year that using an external antenna can be a problem during a thunderstorm as the lightning can foul up the inner workings of the radar unit. As an aside, I run a Boltek Lightning detection unit which can alert me to developing thunderstorms in my area. When it starts popping, I disconnect the antenna from the unit. It's not fool proof but it can help prevent the unthinkable.
