If I mount this antenna by a tree will it hurt the performance?
In the clear is always best but many of us have limitations where are antennas are.
Consider this, Many of us use trees to hang dipole antennas from.
Thank you very much...
Undertaker , I'm sure you have posts on here that tree's don't make a difference , I thought the same . Recently I had 8 huge oak trees taken down ( My XYL's deal ) . Wow what I difference my receive on my A-99 has improved almost 100 percent
and my output I get compliments on . Local Op's think I'm running my new amp I'm not ! Just my barefoot Cobra 2K , I save the amp for " Good " Dx . JMO
This will be my second base antenna how far away does it need to be from my siri tornado?
I can't say how much it would affect the performance you would have to mount the antenna 30 or 40 feet away and then have a way to test the idea with another station far enough out to give you a result that you can say is based on it being real close to the tree and 30 ft away from the tree. But if you mount it to close to the tree you could give the tree brain cancer? Sorry, could not resist a little humor.
I would do at least 37 ft minimum
What about 34 ft?
Even a couple of wavelengths apart can still cause some interaction. 1 wavelength should be fine.
Why 2 verticals?
Don't have money for a tower or a beam...
You'd be better off running 2 of the same brand/type antennas and phasing them. They can be phased to run like beam.
Do some research on vertical antenna phasing and see what works best for you.
Undertaker , I just checked Sirio 27-4 beam is @ $150 . I paid less than that over a year ago , but mine is still in the box because of no help to put it up . I had the rotor and box already and the eave mounts are on my house from an old Tv antenna . I'm not going that high because of my elevation ( 30' to my peak of roof ) but a little more $'s you could be Sweet ! Someday I'll find out ! Jmo 73 and God Bless , Leo
Actually I just checked again ( It's $159 ) it comes from DNR and you get Free Shipping if you buy it through Walmart .
No you won't hurt it mounting it near a tree. Whilst trees block VHF and UHF they're effectively invisible to RF.
