Actually yes, particularly after a windy night... but 10,000??? _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations
I believe they are rated the same as BNC connectors... 500W... but I've used them with high power for 30 years without a failure... I also used a Waters wattmeter for years at high power... and it us
out of the antenna due to impedance mismatch and radiator inefficiency. In other words, if the SWR was 1:1 and the antenna wire was a perfect radiator, the termination would dissipate 0 watts." Now
Right... the folded dipole is 4x the open dipole impedance... not 2x It's my memory that failed me ;-) _______________________________________________ See: http://www.mscomputer.com for "Self Support
I sure wish it was that easy! no... it won't work... not even a meaningful reading is possible that close to the ground. Pointing it in the air, reflector down, will tell you if you are in the ballpa
Hmm... I just put up 10/15/20 monobanders on my 150' guyed tower... just too high and inaccessible to take a chance on a SteppIR... but I have a "problem" with the tuning of the 20M antenna... and it
I'm not sure that's necessary... they could use a Hi-Q loading coil... this would work well since bandwith isn't the issue it is with a more conventional shortened 40... it wouldn't have to be much b
Just thought I'd let you know what the problem turned out to be Bill... I had started with a new 205BA which I'd had in storage... I converted to a 205CA... but I missed something important... The ce
I use 3 5 el yagis stacked in a tree... With 7' between the 10 and 15 and 10' between the 20 and 15 the performance is as follows. 20M... virtually unaffected... 15M... loss of about 1DB forward gain
Not really. I used an inverted vee... apex at about 120', and had absolutely no trouble being heard in Europe... OTOH hearing was a problem that I did not resolve... no room for beverages. However fo
Considering the hassle putting it up... and the problems possible with traps... and the fact I'm a little skeptical about it being up for 3 years... those antennas have been around since BC (Before C
Andy But after you already have the bigger antenna... I have a high-power unit that I've been running QRO for years at home... Made by Microwave Filter Co. I'm not sure if it's still being manufactur
You may be interested to know, the pilot in question was an active ham, well known on the local 146.76 repeater. He was also a very experienced pilot... hard to imagine what went amiss... possibly de
I don't use a steppIR here (yet) and I can never see it being my primary antenna... just don't trust it's complexity... but I don't see cost as being an issue. Any solution that gives good performanc
Unless you are aiming microwave dishes, I think a pier pin is a better sollution to avoiding torque stress on the tower. _______________________________________________ See: http://www.mscomputer.com
I'm a little bit skeptical of this issue... a typical tower 120' tower using 80% radius for guying at 3 points is going to have a guting radius of 240% for the bottom set of guys... at which point te
This tired argument about "lowering property values" is what irritates me... especially on a treed lot. Nosey neighbors lower property values... who want's to live next door to one of those! Even if
I also used to like to work on the tower at night... I found there was much less sense of height, so I found it less "stressful". tower work _______________________________________________ See: http:
I use an Array Solutions switch. Works great... even on 2M with a bit of an impedance bump. Very solid construction with the exception of the tower mounting arrangement which I don't like.. _________
