Yes folks can make contacts with Arrow and Elk antennas because it is done every day of the week . . . . that is not the argument here . . . my comments have been made to give full disclosure of the several issues which seemed to be ignored by advocats of one over the other . . .
Arrow and Elk are LINEARLY polarized antennas . . . . the 17,000 mph moving satellite is throwing off CIRCULAR polarized RF energy . . . please SUBTRACT 3 db or more of gain from your Elk or Arrow when receiving the satellite's signal . . . some still do not understand this concept and never will . . . ignorance is bliss . . . .
For years I grinned ; like I am doing now whenever I saw an 18 wheel trucker with a pair of 3 foot high verticals and a big coil of aluminum tubing at the bottom . . . . probably a good analogy . . . . yes they can make contacts for a little distance just like users of the Arrow and Elk can make contacts . . . .
yes "field tests" ( anecdotal evidence ) give you some sense of satisfaction . . . . some CB ers enjoy CB operating too . . . ignorance is bliss . . . . .working a buddy across town from his house to yours on 2 mtrs or 435 mhz is one thing because your antennas are not moving . . . . once one of them starts moving quickly ( 17,000 mph ) it all changes . . . I realize that this requires some further reading, studying and understanding . . . .you need to understand the entire story . . . . ignorance is still bliss for far too many . . .
up until about 1952 folks used monoband beams . . . . then the triband beams with traps appeared . . . degradation occurs one small step at a time . . . it is progressive too . . . now we have folks doing CW with their computers during contests and they think that they are CW ops . . . . . . note I did not say sending . . .
a couple of locals were all in a lather a few years ago when the local DX packet cluster went down . . . what are we going to do . . . I told them it really made no difference to me as I will continue to TUNE the bands for the DX . . . because that is what a DXer does . . .
the DUMMYING DOWN of hams is sad . . . of course it depends upon your base of experience . . . . if you do not know any better . . . well ignorance is bliss . . . we do need fuller disclosure to the newbie who asks a question . . . .
If somebody says : yes I know all of that but this is my compromise; that is fine . . . but folks are preaching to folks who ask questions : what should I buy ? . . . . there is another option which is being ignored . . . thus my questioning to let the newbie know that these antennas work but there should be a caveat of the compromise . . . without that caveat or understanding they think they are on the Gold Standard . . . ignorance is still bliss . . . in other areas we call it :
1) doing due diligence or 2) informed consent . . . . some folks hand over all their money to somebody else to manage . . .oh yes . .. ignorance turns from being bliss . . .to catastrophic . . . but it goes on and will continue . . .
Some folks are selling these antennas like some sell religion . . . with certainty that theirs is the one true one . . .give the newbie the FULL STORY please. . . that has been my goal for several weeks now . . . I have received many nice personal emails thanking me for my comments . . . I am not bashing ARROW or ELK just trying to give a FULL DISCLOSURE which is what should be going on not just blind advocacy for one of these over the other . . . . which is mostly what I have seen with anecdotal comments . . .
