Can this amp be used on FM mode? I've not been able to confirm this as the user manual only identifies CW and SSB

All of those are real nice however, I have a DOT hight limit of 13.5 feet, and the top of the truck is close to 12 feet so, it has to be collapsible in order to be legal on the road. That's why I'm going for a telescopic fiberglass mast with either folding or removable elements. It cannot be...

Yup, i did type that backwards. Derp. I considered a fan dipole but, it's all about the deployment. I need something that can go up and down with minimal conflict while mounted to the back of a semi truck. There are proximity conflicts all over the bottom 13 feet of elevation. I started thinking...

Actually, I'm starting to lean towards three pairs of tuned whips, each with a roll pin inserted through the wrench flats to facilitate a wingnut kinda thing. This way, depending on what my SDR is showing, I can quickly connect the band specific whip pair, hoist, then fine tune with the antenna...

While trying to design a 10-12 meter horizontal dipole for use in a portable installation, I'm trying to decide if it's better to utilize 2 standard stainless steel whip antennas, cut resonate for 12 meters and utilizing a stainless steel coupler to extend the tips to resonate at 10 meters when...

I will. I'm looking at a 21' collapsible mast using a couple quick locking truss clamps. This setup would resolve all my issues and provide outstanding TX/RX. Thanks for the idea!

Hmmm. That's an interesting idea. I did consider this option in a vertical orientation however, in one placement, the lower half would be behind the cab...not sure that would work...or I could raise the entire assembly 10 feet up. I never considered doing this horizontally but, that could be...

Oh. I figured given his advanced age and the fact that his posted email address rejected my email to him, he must have passed.

I can't really do an Antron due to storage issues and such. My motivation for 10 meter is rooted in combination transceiver options. The Galaxy 94vhp can be modified for both 10 and 11 meters, using an amp switch to power down for 11 meter use. I have limited space in the cab for hardware. I...

I fear that I was too vague about the conditions while in use: Disconnect and dismount the 10 meter whip using Breedlove quick disconnects, and switch coax to 11 meter antennas while underway. Remount 10 meter whip using quick disconnects and switch coax to 10 meter whip while parked for the night.

Yes, I've read quite a lot on that site already. Guy sounds like he knew just about everything there is to know about antennas. I wish I'd had the opportunity to talk with him about this before he'd died.

Thank you for your input. I have considered this also but thought that I would get a better omnidirectional, low plane radiation pattern using a vertical. Using a horizontal would place the element very close to the freight loaded on the flatbed trailer. I could simply use quick disconnects on...

Ok, perhaps this might not be the right forum to find an Elmer but, let me break this down Barney Style for those of you who have confused this thread with Twitter: I have cophased 11 meter band top loaded antennas for use while underway. Once parked for the night, I can climb the ladder and...

I think you may have missed the part where I'm using Breedlove quick disconnects because, well, obviously.

Thank you for the reply. Yes, my only motivation for phasing 2 antennas is to reduce the dependence on a ground plane, given the limitations of my installation option at such a height and drastic change in metal surface from the 0 degree to 180 degree position, I'm trying to avoid a poor ohm...
