My rule of thumb is that no tower should be close enough so that it can fall on a guy wire holding up another tower.... and so on. The Domino effect..... RF wise, mo' is better. Adjacent bands here a
Hi Jim; Well it will be close, judging from the dimensions. The rotor will fit in Rohn 25 (no cutting diagonals needed) but the motor does protrude a bit. inches. After doing the math on a 14" triang
Well, the earlier models did not have the reversible scales - not sure when it came in, but you still may be out of luck. If not the black plastic later model cabinet, I doubt it would be there. 73 D
See if anyone does augured in / screw in pilings in your area. Basically a pipe with one helix (or more) welded on the bottom. Install 3, and then mount your tower on that. Tops are generally joined/
Count me firmly in the side that approves of guying a self supporting tower. And I can personally attest to VE5RA Doug's experience with guyed Delhi structures - he has been there and done it and the
Just in cae I confused anyone with my reference to VE5RA, I was living in the past. I should have said VA5DX..... tower. with plus a Weather Stations", and lot's more. Call Toll Free, 1-800-333-9041
Many rotator motors are now DC. And the current method is fine as long as you have not yet installed the antenna (or no wind if you have). I take a small 12v 2 amp/hr gel cell up the tower, plenty of
An alternative base system often used up here (Edmonton, Alberta) is to screw in some piles, weld up some base feet and put up the tower. No waiting for cement to dry. And the hydraulic auger unit ca
Quite the imposing structure on the skyline. True beauty - for those that read this reflector anyway. I'm curious as to why the elements are that large, especially at the tips - they are still about
I'm in the process of rebuilding a M2 2 el 40m yagi - I think it may be the model 40M2LP altho it may be an earlier version as the linear loading attachment looks different. And yes the linear loadin
This would be natural if energy from AM broadcast stations is enough to partially mask the minimum SWR point. I am over 100 km from nearest AM transmitter but the MFJ is pinned on any 160m dipole I'v
I speak from personal experience (in trying to test to destruction) in saying that the AlfaSpid rotor wouldn't have any issues handling these kind of side loads. The rotor design has 2 steel pipes th
I've used them for years here - not the wireless ones - but the cheap 1/3 CCD B&W type, mostly purchased at Dayton over the years. I have too many towers to monitor and the distances are a bit much f
I have contemplated using these if I could find enough of them (10) at a reasonable price. The article mentions aluminum but all the ones I have and have seen are steel. Either could be very usable,
I sometimes wonders if antenna rotors don't acclimatize to their surroundings..... I am amazed at how high a temperature I have heard people comment on that their rotor is froze up. Up here a balky r
If the "gunk" happens to be some form of NoAlOx compound that has dried, it can be very tenacious to remove. But a shot of WD-40 and it just wipes right off..... 73 Don VE6JY the ____________________
I would make sure any guy wires are broken up by insulators so that no DC current (caused by the difference in potential of the different ground points) would flow into the ground thru the anchor rod
I have owned a Trylon in which most of the upper sections used rivets. This is not the norm, though. I believe it was quite an early model - or someone choose to use rivets - as I would agree that cu
I won't comment much on alfaspid.com redirect issue, many of you have told us about this so we have been aware of it for some time. To address Roger's (K8RI) comment - I too had some concerns when I
It is certainly a method I like to employ when at all possible. Our rotor allows 720 degrees of total rotation and that can be sometimes hard to achieve using the traditional big drip loop of coax ta
