Yes, and you will have plenty of cross modulation due to the very many lousy connections between the different metal sheets. You have the same problems receiving, as you will have the same cross modu
Why don't we try something like that? Maybe it could save us a PA or two.. Hans - N2JFS --Original Message-- From: Steve Sacco NN4X <nn4x@embarqmail.com> To: towertalk@contesting.com Sent: Thu, Aug 1
First problem; your beautiful, very well generated, filtered and harmonic free output with harmonics maybe, well below any possible regulation (say -180dB even if this is unrealistic) could easily be
If you only have two signals present you will see an extra signal between the two signal plus weaker signal on each side of the main signal. It is the difference between the two main signals that is
I realized made an error describing the product of cross-modulation: If you have only two signals present you will find cross-modulation products that are related to the harmonics and mixing of the t
I dealt with two signals only, just to make it simple. If you add modulation, other signals etc. you end up with CM products from ALL the different signals. That makes an almost continuous band of si
The problem you will have is not necessary the writing but the CC&R board. They may simple come and tell you to take the tower down for whatever reason. I would, myself stay away from anything that e
I believe they use something around 2.4 GHz, near the "water line". Please correct me if I'm wrong. Hans - N2JFS What frequencies are they using that are so susceptible to weather and foliage? I've h
The conductor and shield are silver plated. Silver reach with sulfur that eventually reaches the inside. Silver-sulfide is black. Hans - N2JFS --Original Message-- From: Tom Osborne <w7why@verizon.ne
Sorry for the mistake. It appears that water absorption is not tha easy matter as a peak somewhere. Check http://www1.lsbu.ac.uk/water/microwave.html for some more details. The "peak" appears to be v
How easy would it be to arrange an I-connection on UHF? We did relatively good linking all our digipeaters together and go one step further should be possible especially with all the towers we have u
Ah, so true! So, what you are saying is that I should have applied for a tower to use for InterNet access purpose? Hans - N2JFS First, the OTARD rules contain provisions for wireless internet, essent
Beside a HiPot test you should look for the "silver mirror" inside the cap. Normally, I think that's the case for vacuum caps as well, there is a barium film deposited inside the glas envelope. The f
You better think again, Roger, Your line begins where your contract with the utility says it begins and that may be anywhere between you and the utility company. It might (not necessary every time) b
I wonder if a north-seeking, plastic owl can do? Hans --Original Message-- From: jimlux <jimlux@earthlink.net> To: Alan NV8A <nv8a@charter.net> Cc: TowerTalk <TowerTalk@contesting.com> Sent: Tue, Aug
I believe the "Plastic Owl" first was mentioned (at least to me) when the discussion lost track in trying to find out the best method finding true north. It has, after that shown up as an indicator f
MOV-s are useless at these frequencies. They can't even be used for protection of phone lines. Gas arrestors have the low capacitance you are looking for. If you check out a surge protector for phone
Hi Jon, I have a 250' windom made of #14 and I had a 250' Windom made of #12. They were both supported in the middle as well as the ends. 1" of ice made them both to come down. I had similar support
Thanks! I an idea. I can support them with the tube. The tube will break before the wire, thereby saving me from splicing the wires. You shall know that the ice can build up to inches and it doesn't
Somehow I am not really comfortable with having a power supply connected to my antenna winter through. There need to be a balance between melting the ice and not melting the wire. I am not sure I wil
