August 2012 Q&A on this related antenna subject
http://www.eham.net/ehamforum/smf/index.php?topic=84914.0

The 40/80-meter dipole (trapped, loading coils, fan) was very popular from 1950 to 1980 with Novice operators.  
The antenna would often function well on 15 meters, using the 40-meter section as a 3/2-wavelength dipole.

Designing a Shortened Antenna

Bill Fanckboner, W9INN (sk) designed, built, and sold a number of shorted wire antennas
until 2004, when he passed and his family shuttered the business.
http://www.qsl.net/n0nv/w9inn.html

All of Bill's antenna designs used only 2 dipoles/elements (fan dipole).
Bill's inline coils (Resonators) are 2" OD forms (dark gray) and coil length 2-1/2"
with the plastic form longer for wire attachment (5 to 12 inches common)
One foot wooden dowels are used to separate the two dipoles.

Actually I was looking for Chisel tipped one that looked like the #4036 with the ceramic element, not the long metal element ....
That would be an Ungar 45 or 50 watt heater element (Ungar used ceramic for insulator due to high heat ~ 1100o F) with an Integrated Chisel/Screwdriver tip.

However, as I noted to you earlier, Fabrication/Production changed after Weller acquired the Ungar products -- some of this was RoHS compliance required, other was for easier production methods.  Weller has discontinued many Ungar ceramic heating elements.
These models are popular with the Stained Glass Industry.
http://www.glassmart.com/ungar_45_kit.asp

The Integrated Long Chisel Tip with a 45 Watt heater is part # 4033.
The Integrated Short Chisel Tip with a 45 Watt heater is part # 4039.

Arcade Electronics, near your QTH, has parts stock !

You will need the Ungar part number to inquire, Chester Electronics in Kenosha, WI
 has some Ungar inventory still left.

The 1233S and 533S appear to be screw on tips, and I find them not as acceptable to the larger items I want to solder since they won't sink as much heat.  
NON-SEQUETER.

You asked for a LOWER WATTAGE (33 watt) and
desired a Chisel Tip that is Integrated with the Ungar Heater.
Modular Heater with Integral Long Chisel Tip, 33 Watt, 900°F: # 1233S

That is EXACTLY what part number #1233S is.
I HIGHLY suggest that you purchase more than one, IF this is the tip you desire !!

In the late 1950s, QST magazine featured a number of antenna designs.
Many of these designs became the commercial antennas or antenna parts,
that are sold today by Hy-Gain/MFJ, Hustler/Newtronics, Mosley, Cushcraft/MFJ,
Butternut/Bencher, Reyco/Unadilla, Mini-Products/TCM Communications, etc.

In 1957, Ralph Rosenbaum, W5ECP designed the 20 meter Wonder Bar antenna.
The W5ECP antenna project was published in June 1957 issue on pages 44-45 of QST magazine.
http://p1k.arrl.org/pubs_archive/38975

Here is an updated DIY Build of this 20 meter Wonder Bar antenna.
http://www.hamuniverse.com/20meterwonderbar.html

It was a scaled-up version of E.T. Bishop's K6OFM's 10-meter "Wonder-Bar" antenna
published in November 1956 issue on pages 32-33, 138 of QST magazine.
The E.T. Bishop design used readily available Biconical TV antennas to fabricate this antenna.
Since it looked like a common 1950s TV antenna, neighbors did not complain, in this era.

I see you asked this same question in December 2012.
http://www.eham.net/ehamforum/smf/index.php?topic=86764.0

Gotham Antennas (Miami Beach, Florida) is no longer in business.
http://www.w8ji.com/gotham.htm

Bencher acquired the assets of the Butternut Company founded by Donald Newcomb, formerly of Texas.
The Butternut Butterfly was a popular antenna, in this compact size.
http://www.bencher.com/ham/index.php?main_page=product_info&cPath=4&products_id=15

One other possibility is the old Mini-Products (Erie, PA) HQ-series hybrid quad antenna

Tom McKay, VE3KVD, of TGM Communications (Stratford, Ontario : Canada) acquired the
Mini-Products antennas and re-named / updated those antennas to their MQ-series.

Weller purchase Ungar Soldering in 1996.  
Some old Ungar models were discontinued by 2000 (millennium), while others have been slowly discontinued since 2003.
Weller had to rework its entire production operations for RoHS compliance, which they did when they moved production to Mexico.

Ungar's old Edison screw-on soldering iron handles are sold/supported (heaters: 45, 33, and 23 watt), with an integrated soldering iron tip OR
with interchangeable threaded soldering tips.
You need to WATCH, as Weller has discontinued some slower selling parts (wattages, tips).

The Ungar 4036-S is a Stainless Steel Heater - 45 watt - 1100 degrees - Pyramid Tip
Arcade Electronics (Washington DC area) has that part IN STOCK for $34
http://www.arcade-electronics.com/Ungar-4036-S-p/ung-4036-s.htm

There is a 4036 Iron Clad Silver Plated Tip 50 W for sale on eBay for $19 from a Pennsylvania seller, right now.
eBay Item Number:  321085885701
===
You stated you desired a 33 WATT Heater / Tip.  HERE are those part numbers, with an integrated heater and iron tip.
These heater/tips are used with Weller/Ungar standard series modular irons SL325, SL335, SL345 and SL500

Modular Heater with Integral Long Chisel Tip, 33 Watt, 900°F: # 1233S
Modular Heater with Integral Long Chisel Tip, 23 Watt, 800°F: # 533S

The other Heaters sold in this series permit a screw on soldering tip (more flexible).

Pure metallic Lithium is stored is mineral oil or other oil solution to prevent reaction (water in air/humidity).
I saw my first demonstration of a chunk of lithium (size of one Vegas dice cube) and Water in high school chemistry -- safety glasses were mandatory.  Typical of Clark's experience, explodes into flame.  It is an Exothermic reaction, so the heat released often ignites the hydrogen gas given off.

Lithium reacts intensely with water, forming lithium hydroxide and highly flammable hydrogen gas.
The colourless solution is highly alkalic. The exothermal reactions lasts longer than the reaction of sodium and water, which is directly below lithium in the periodic chart.

2 Li(solid) + 2 H2O -> 2 LiOH (aq) + H2(gas)

At 750oC lithium reacts with hydrogen to lithium hydride (LiH). The white powder that forms releases hydrogen gas upon later reaction with water, in amounts of 2800 liter per kilogram hydride.
As such, lithium is always studied for its application as hydrogen storage.

Seawater contains approximately 0.17 ppm lithium. Rivers generally contain only 3 ppb, whereas mineral water contains 0.05-1 mg lithium per liter. Large amounts of lithium were found in holy water from Karlsbad, Marienbad and Vichy. In solution it is only found as Li+ (aq).

I placed an order online this past weekend and have yet to hear from them. Is the Wireman still in Business? If not why is the website still up and running? I hate to think that my credit card number is just sitting there for some hacker to find.
Roland -

I placed a regular order (telephone) with The Wireman same week you posted.
I use the telephone, since I usually pick-up "end of rolls" (coax, antenna wire, rotor cable) that are Specials or Clearance items (First Come, First Get) -- added to my orders.
I also check on some items that are getting harder to source (ladder-line), due to only one cable mfg. in USA still making it.

My Order arrived promptly a couple days later.  
I have been dealing with Pres, N8UG since late 1970s.  
Today, his staff / family handles much of the day-to-day orders and
he doesn't attend the number of hamfests that he use to attend 30 years ago --
but neither do I !!
--
They are planning on attending Dayton, hope for good weather.

BTW, DX Engineering with their nice Internet merchandise web site ($$) have a full-time staff working on Internet.  They have made mistakes with my orders in past -- BUT we have always resolved the issues with a telephone call or e-mail.  Part of the e-commerce game.

Quote from: W1AJO
Last June I purchased a Hy-Power 2 band dipole 2B2040LQ and finally got it installed today. 
As I live in an HOA subdivision, I had to install it in my attic.  I just noticed in the instructions that it is not recommend it for indoor use.  Perhaps that is why I am having SWR & resonance issues with it.
Your Newnan neighborhood is HOA?
I think you should be able to install a dipole or wire antenna at your pine tree line.

Like the W9INN(sk) and Alpha-Delta antennas that use loading coils (inductors) to shorten the antenna's length -- nearby objects, especially metal, will easily de-tune them (high SWR).

I don't know Barry, KU3X tuning setup for these antennas, but Bill, W9INN(sk) tuned his antennas at 35 to 40' above ground.

Quote from: AF5FH
WB2WIK, I will take the soldering iron up to the roof with some solder. If it is a cold solder joint, that would be Hy-Gain fault, and I can fix that. If one of the tuning spokes is loose, then it would be my fault.
Tin/Lead solder & a soldering iron will not resolve (fix) Aluminum connections.

Due to the weight/mass of the upper section on this antenna (and R7, R7000, R8), IF this antenna did not have small non-conductive guy wires -- the constant flexing in wind can loosen connections.

The new Cushcraft R9 states usage of guys, for the same reason.

The Motorola console is a common remote base frame (vacuum tube).
Various modules could be added to that case.

My Dad had one, when he built his office in town (early 1960s) -- it remotely operated (via dedicated telephone circuit, 2 or 4-wire) the 46 MHz T radio at our house.  Operated that way until 1990.
