Yes, it was QST July 1963. I did visit Dale during the summer 1973, that antenna was still up on the tower however broken. The boom had snapped and the part was hanging down in the boom guywire. Sure
What ever did happen to N7ML? I used to work him all the time on 80m LP but all of a sudden he was gone, I haven´t heard him in years. _______________________________________________ __________
IMO not true. It´s like this, NEC-2 code has problems with close spaced wires and wires close to the ground, MININEC can handle situations like this better. However the MININEC code has some ot

Why not use the real thing! If you like I can send my friend over to you, however it´s a long trip so it might take him a while. http://sk3w.shacknet.nu/sm2ekm/view_photo.php?set_albumName=SM2E
Not free but the software "antenna model" looks interesting since it does have some corrections to the MININEC code http://www.antennamodel.com/mininec.htm With MMANA one has to be careful due to the
Sounds like you mean a Hardydisc. I have used one on one of my rotating towers for years, my unit came from a Ford Granada station wagon. Sure is a good way to protect a rotor. By the way, also to ge

However then its NO 204BA any more! / 73 Jim -- Bob Maser wrote: That's easy to do. Take a 5 element 205BA, remove one of the directors, run the YO antenna modeling program using the 34 foot boom and
I dont expect anything however its totally wrong calling that antenna a 204BA, its something else but no 204BA, its a "former" 204BA. /Jim SM2EKM -- Bob Maser wrote: Surely you don't expect a 4 eleme
Instead I would measure the loss in the cable, then I would know for sure. _______________________________________________ _______________________________________________ TowerTalk mailing list Tower
Wow what a beautiful picture. I have heard it too. There is also a station from Seattle on 1000 kc/s (I think it was) that thunders in. / Jim SM2EKM '''''''''''''''''''''''' _________________________
Me too! I even did some operating from W8SH a looong time ago, think it was 1973. Even remember some fun I had back then in Lansing Mich. Jeez those where the days! __________________________________
Yes very much needed, depending on antenna heights ofcourse. Forexample, I once had a 5/5 20m stack at 100/47 ft then it wasn´t needed. My current 20m 5/5 stack is at 130/65 ft and I couldn&acu
Yes agree, lower alone would have been OK. However this was the only test I did, I can´t switch upper or lower alone. I wanted to keep it simple and also retain stacking gain, runing BIP/BOP IM
At least not me, I´ve used crimp PL259´s for 25 years by now however these days I mostly use 7/16" stuff. If you ever need to replace a connector up on a tower it´s sure nice to hav
Yes this works excellent. For very high power you can use RG217 or even RG17. Right now I have about 10 Yagis using this type of gamma. I´ve measured this and for me it gave much better return
No it can be measured without cutting off the connectors 73 Jim SM2EKM -- Roger (K8RI) skrev: _______________________________________________ _______________________________________________ TowerTalk
Thats not what I mean to do. Just use an old style Ohm meter, something like the old Simpson 260 or an old Sanwa or something similar. Then use the highest ohm range, you like to be able to measure 1
