Wonder how well that would work horizontal? Not an antenna guru.
It's a dipole....can be used both vert and horz. Might be easy to get up there. Tune it down on ground, after your tree monkey anchors it test and tune to get swr just right.
It might be the easiest to mount, just need to trim up one side of the tree.
I like how the old one is stealthy up there. I'd just cut enough to allow for movement of branches not to tear up new antenna, whatever one you decide.
This isn't climbing a tree, but my toes (and other parts) were scrunched up watching this video full screen / surround sound
IMAX 2000, up in the tree works for me.
I wish I had a tree
That might be what my pinetree will look like after the new install. lol
What kind of coax are you running to that imax?
Times Microwave LMR400.
That what I'm going with this time around. 24 years ago I didn't invest much in coax. Not this time around. This time I'm putting money in the wire.
Amazon has Tramflex 8X. 500' for $107
Davis RF has BuryFlex for .89/ft.
Jefa Tech low loss 400 $0.69/ft and its direct burial too. I have 100 Ft going to my Vector 4000.
JEFA Tech Low Loss 400 is a high performance alternative to CommScope® WBC-400, Times Microwave Systems® LMR-400, Belden® 9914 / 9913 / 7810 and Andrew® CNT-400 coax cable.
This is high performance coaxial cable which has become the standard of the outdoor wireless LAN industry. It is also used by Amateur Radio stations looking for higher performance for VHF/UHF, microwave, and satellite communications as compared to standard RG-8/U. It also works very well on HF, with much higher power handling capability than other coax alternatives. GENUINE BRAND NAME COAX CABLE
