Have my vertical working great and have a small Delta-loop low band receive antenna BUT the Ten Tec Jupiter doesn't have a separate receive antenna like a K2, for instance (I borrowed a K2 to try out
Ahhhhhhhhhhh...luv it when K.I.S.S. idea passes by, Tim....I can do that!! So simple, how come I didn't think that solution up!! Much appreciated! Jim R. K9JWV _________________ Topband Reflector Arc
Yup, Doug...I'm already "shopping around" for the relay....hi hi Tnx for the bandwidth, all...I'm ON IT! _________________ Topband Reflector Archives - http://www.contesting.com/_topband
I am nervous as well, Tom...hi Hi I'm really thinking of employing a separate relay that I control with a simple switch, vice depending on the rig to switch "correctly" using a simple switch is antiq
I've used the loop and a KD9SV preamp with the vertical before, JC, and no overload problems ...I run QRP power during Top Band contests. Your cautionary notes are noted and appreciated! Jim R. K9JWV
A friend of mine is building me a switching arrangement with a reed relay to switch between my transmit antenna and a receive delta loop to the one antenna input for my Ten Tec Jupiter (I operate at
Thanks to all for the insightful replies/advice. It would appear the use of clamping FETs is worth a try... 72, Jim R. K9JWV _________________ Topband Reflector Archives - http://www.contesting.com/_
Oooops - sorta!! Checked the schematic for the KD9SV pre-amp I have and find it does have clamping diodes at the input...DUH.....so, question/problem/concern resolved, in spite of myself!! Hi Hi Tnx

This is the title, Short Antennas for 160 Meter Radio - anyone read through it? I have ON4UN's book from a couple of years back so wonder if there is anything worthwhile in that ARRL version ... than
Thanks to all that replied - enuff "keep reading the ON4UN tome" comments to keep me from reaching in to my wallet for a charge card...Hi Hi Hope to hear and work you in the upcoming CQ 160 'test' th
Do the two verticals require any type of radial system or can a simple "array" of 4 to 6 20' radials do the job?? 72, Jim R. K9JWV _________________ Topband Reflector Archives - http://www.contesting
Besides "optimim number(s)," I wonder if there is supporting analysis for the connection of the radial ends?? I have around 80 elevated radials that range from 50 foot lengths, running east and west,

Carl: I've read, at several places, that sleeve baluns are effective at VHF and above but not at HF frequencies..thoughts?? 72/73, Jim Rodenkirch -- former Tempest inspector for the U.S. Navy..ahhhhh
They'll be offering a 250 kHz to 500 kHZ version later, Carl, to sell ya! _________________ Topband Reflector Archives - http://www.contesting.com/_topband
