[TowerTalk] TowerTalk Digest, Vol 168, Issue 49

[Bryan Swadener]

I like my F12 C-4XL a lot. Yeah, it's not as sexy as a SteppIr.
However, it does what I want, and it cost me a small
FRACTION of the least expensive SteppIr.
It gives me 2 full size elements on 20 & 15m, and 3e on 10m(2 driven elements) for low VSWR on those bands. 2 linearloaded elements on 40m gives me about 100 KHz BW.With my rig's ATU, it plays on 12, 17, and 30m.
The C-4XL = C3 + EF240 on a single 30' boom.I decided on buying the C-4XL, after I bought and read"HF Tribander Performance - Test Methods & Results"by K7LXC & NØAX.
The C-4XL multisection boom quickly/easily partiallydisassembles, allowing me to tilt my tower completelyhorizontal. I perform ALL tower & antenna work withboth feet on the ground.

Subject: Re: [TowerTalk] Multiband yagi w/ 2 el 40m suggestion

>  I'm looking for options for a multi-band yagi (either  10,15,20 or
10,12,15,17,20) that includes 2 el on 40m that could be installed  on a
medium duty 50'-60' crank-up while keeping in mind the smallest  footprint
possible for a city lot. I'm know Optibeam has several options and  I think
Force-12 has one. Are there any other manufacturers that I'm missing?  I'm
trying to gather all my options and compare the specs.
 
    If it was me, I'd get a 3L SteppIR with the 30/40M  trombone element. 
Lots of band coverage and a monobander at all frequencies!  Can't beat that 
and it fits your smallest footprint parameter. I think they have  one with 3 
trombone elements that would result in significantly reduced element  
lengths.
 
    I don't remember the specifics but I think Force 12  has a couple of 
models that fit your criteria. I'm not a big fan of their linear  loading 
scheme but they seem to work. 
 
    FYI for a rundown of a bunch of tribanders with  measured on-the-air 
performance, get a copy of our on-the-air tribander  comparison report. It'll 
give you some insight on which manufacturers offer  decent antennas and 
which ones don't. It's available from championradio.com.
