Question: The connection plate at the bottom of the antenna is suppose to be earth grounded correct?
Document: This is my second Imax, first destroy when winch broke on mast, I would have rated this one a five star but antenna connection was not centered at bottom of antenna. It tuned to 10 meters very well, can't seem to get the swr's down on it on eleven meters, but I will buy another one. I know they are good antenna's.
I believe that there is only a simple wire in the middle section and perhaps the connection (solder job) is not quite perfect...... there may be a problem in the future for me.Worth the bucks?
I also put one down at the shack.The RF noise choke consists of the RG-8 coax feedline. The normal feedline you use to get the signal into the shack. I left a 6 inch pig tail for the antenna connection and then wrapped 12 turns around a 2 inch piece of PVC pipe about 8 inches long - making a coil around a PVC form secured with black zip ties through holes punched in the PVC pipe. It looks like a big wire wound resistor, but it works!
Perhaps earth ground, which lowers the SWR, is reducing the antenna efficiency to 60% when I lower it to get a good SWR. I am using EZNEC at this time to explore that.> Contacts. As a new Amateur operator on the HF bands, looking for an inexpensive way to experience a few contests, make some good contacts, learn the protocol, and not offend my neighbors with a big antenna....this antenna is working for me.
This mount is not grounded by a ground wire. It is mounted to the tripod with a 8 ft. piece of pipe and I ordered and installed the Solarcon radial kit. No other radial or ground counterpoise was installed. The roof has normal composition shingles. The antenna is about 18 ft. above ground level.I am using a very old 100' run of RG8 coax dating back to the early 1980's with silver plated Amphenol connectors. It is old but in good condition.
I assembled the antenna in about ten miuntes,and have it installed on a 10 foot mast.
If your into skip like im not then this antenna will do the job. seems to work pretty good barefoot.
I am enjoying this antenna on 10 meters and it seems to be working well. It has met my needs.
A friend had this antenna and recomended it & he was right, plus it's made it's very sturday for the high wind at my place.
Just not sure how long this &#34;Flimsy&#34; Antenna will last. Working on the second one ! Guy wired & all
Answer: Mine is mounted on a 40 foot mast, and I just grounded my mast not the antenna.
