I presume the shortest ingredient that's the much larger diameter tube to be for the higher freqs, with the massive diameter allowing for these a large bandwidth, and the other factor pairs to get for The 2 VHF band sections. My antenna analyzer only goes as many as 170 MHz. I'd like to see the whole plot as much as one GHz.
I have yet to buy one of such antennas although, mainly due to cost. Quite Truthfully I'm astonished that it performs that a lot better than the usual scantenna does. It certainly is way more rugged.
Quoted: I don't see any storms around the radar, or any photos of a whole new antenna mounted up large possibly.
The aluminium tubes that sits around the plastic tube are tuned to all over 400Mhz and therefore are so huge in dimension that it perhaps addresses 100 MHz vast frequency vary. The X aspects are tuned for VHF-Air and VHF a hundred and fifty-170MHz.
I am asking yourself if I would be greater off using a Discone and 900MHz antenna then use a diplexer, but if I could get it done with a person antenna that will be awesome.
I am not seeking to be wise or hostile, I'm just seeking to give a sense for the trouble which includes to go in. Trust me, if it was me And that i didn't know greater, I too would likely evaluate it and Feel, what is the huge offer? But it is just one large pile-o-labor to make Those people items, allow me to inform you. Indeed, CNC is a choice, but that goes again to the money. Individuals who have CNC along with other automation pay for it via either significant person charges, or lower prices as a result of amount.
I think the thread about the $three cellular antenna went on for approximately 3 months. That claims a whole lot about in which the state of mind is for the typical consumer level buyer, and that's not something which evokes manufactures to go after that crowd, once they might make tens of millions in comm and gov sales. I Individually want to build items for hobbyists, but people have to recognize that it requires revenue. That money just isn't ever going to come from quantity, mainly because there isn't any in passion stuff. So it should come from the price. Last of all... In all fairness, for those who think about the couple other people presenting a client grade LP patterns on the market, we remain effectively below the likely industry fee. The other two I'm able to visualize particularly are retailing for approximately $three hundred-four hundred. We are even now greater than $100 below that, and frankly, I don't know how for much longer which can previous, simply because All those other two businesses truly are worthy of whatever they are getting for all those... Labor-wise, the LP is essentially like creating two yagi antennas and sticking them with each other. So if you acquire two co-phased yagis, you'd be checking out it's possible $three hundred?
If it works superior you could possibly utilize a diplexer to possess the Omni-X go around 500MHz tgagrand after which the diplexer will use the dipole for anything at all above 600MHz.
I Individually am not an enormous fan from the do-it-all antenna. It is physically extremely hard to make one antenna do every little thing nicely, but I are aware that's nonetheless what a whole lot of men and women hope for.
timjude claimed: Kinda not easy to think that antenna would hear that properly.Seems like very little much more than a centerfed vertical dipole..but i am no engineer so I can not say Substantially.
The brand new Omni-X antenna is changing the shorter rubber duck on my handheld Radio Shack Pro-106 Scanner, After i'm inside the shack. I have an approx forty five' length of Davis RF 9914F BuryFlex (LMR-four hundred dimension) coax running as a result of conduit in the shack to only over the playhouse roof. I believe the frequencies I've programmed within the scanner from Radio Reference are in the Public Basic safety variety you claimed over.
"Simply a Notice of thanks; Omni X is up at 50 feet to the tower-will work excellent. Thanks for the function and attention."
Construction is like very little I've witnessed for even twice the money. Quite sturdy, very well engineered. I do not Feel serious weather conditions could ever demolish one among Dave's antenna's with out destroying your house as well!
boy you certain skipped out by going having a discone, if you like what the discone does you might have loved this antenna..
